28 \China Science & Technology Education∙研究背景摩尔斯电码（Morse code）是一种以信号通断的时间长短和组合方式传输信息的信号代码。

本人在进行科技活动课和信息技术课教学过程中，将摩尔斯电码收发报的知识和体验活动引入课堂。

学生对摩尔斯电码很感兴趣，但是在学生学习完理论课程以后，我却没法找到合适的、仿真度高的教具和学具让学生体验摩尔斯电码收发报过程。

所以，很有必要设计一套仿真度高的摩尔斯电码收发报体验设备用于装备学校实验室和课堂。

∙项目研究过程　确定项目研究目标本项目研究的目标，是研究一种方法和相关的设备，便于师生在课堂上灵活地分组开展高仿真度的莫尔斯电码收发实验。

该项目必须实现如下目标：①设备成本低廉，便于师生动手制作和使用；②可灵活方便地分组学习；③不会对外发射大功率高频无线电波，不干扰别的电子设备，无须考取业余无线电台操作证书就可以操作；④可自动收发和自动编解码，可对使用者的电码输入作检查与测评；⑤设备外形与使用方法、使用效果具有高度仿真性。

　规划系统各部分的组成架构摩尔斯电码无线通讯仿真实验室的总体架构设计为：实验室里的所有学生组成1个或多个学习小组，以小组形式开展学习活动的科普课堂模式，每个学习小组采用一发一收或一发多收的形式，轮流开展收发摩尔斯电码的活动。

　设计摩尔斯电码无线通讯仿真终端机电路架构摩尔斯电码无线通讯仿真终端机涉及数字和模拟信号的处理，因此电路采用模拟和数字混合的结构，内部架构设计如图1所示。

智能收发一体终端机的应用方法框图如图2所示。

单接收机没有发射功能，也没有智能编解码能力和学生练习的指导和评价功能，架构较为简单，如图3所示。

技术方案仿真终端机通讯链路设计学校教室和实验室是人员高度密集的场所，无论从保护学生身体健康、防止各教室之间的互相干扰，以及收发电路复杂度、成本等各方面综合考虑，都不宜使用常规的高频电磁波作为通讯链路，必须使用一种能兼顾以上需求的通讯链路替代。

DESCRIPTION
The TPA3113D2 is a 6-W (per channel) efficient, Class-D audio power amplifier for driving bridged-tied stereo speakers. Advanced EMI Suppression Technology enables the use of inexpensive ferrite bead filters at the outputs while meeting EMC requirements. SpeakerGuard™ speaker protection circuitry includes an adjustable power limiter and a DC detection circuit. The adjustable power limiter allows the user to set a "virtual" voltage rail lower than the chip supply to limit the amount of current through the speaker. The DC detect circuit measures the frequency and amplitude of the PWM signal and shuts off the output stage if the input capacitors are damaged or shorts exist on the inputs.

Required with the Traditional Class-D Modulation SchemeThe main reason that the traditional class-D amplifier-based on AD modulation needs an output filter is that the switching waveform results in maximum current flow.This causes more loss in the load,which causes lower efficiency.The ripple current is large for the traditional modulation scheme,because the ripple current is proportional to voltage multiplied by the time at that voltage.The differential voltage swing is2×VCC,and the time at each voltage is half the period for the traditional modulation scheme.An ideal LC filter is needed to store the ripple current from each half cycle for the next half cycle,while any resistance causes power dissipation.The speaker is both resistive and reactive,whereas an LC filter is almost purely reactive.The TPA3116D2modulation scheme has little loss in the load without a filter because the pulses are short and the change in voltage is VCC instead of2×VCC.As the output power increases,the pulses widen,making the ripple current larger.Ripple current could be filtered with an LC filter for increased efficiency,but for most applications the filter is not needed.An LC filter with a cutoff frequency less than the class-D switching frequency allows the switching current to flow through the filter instead of the load.The filter has less resistance but higher impedance at the switching frequency than the speaker,which results in less power dissipation,therefore increasing efficiency.7.3.14Ferrite Bead Filter ConsiderationsUsing the Advanced Emissions Suppression Technology in the TPA3116D2amplifier it is possible to design a high efficiency class-D audio amplifier while minimizing interference to surrounding circuits.It is also possible to accomplish this with only a low-cost ferrite bead filter.In this case it is necessary to carefully select the ferrite bead used in the filter.One important aspect of the ferrite bead selection is the type of material used in the ferrite bead.Not all ferrite material is alike,so it is important to select a material that is effective in the10to100MHz range which is key to the operation of the class-D amplifier.Many of the specifications regulating consumer electronics have emissions limits as low as30MHz.It is important to use the ferrite bead filter to block radiation in the30MHz and above range from appearing on the speaker wires and the power supply lines which are good antennas for these signals.The impedance of the ferrite bead can be used along with a small capacitor with a value in the range of1000pF to reduce the frequency spectrum of the signal to an acceptable level.For best performance,the resonant frequency of the ferrite bead/capacitor filter should be less than10MHz.Also,it is important that the ferrite bead is large enough to maintain its impedance at the peak currents expected for the amplifier.Some ferrite bead manufacturers specify the bead impedance at a variety of current levels.In this case it is possible to make sure the ferrite bead maintains an adequate amount of impedance at the peak current the amplifier will see.If these specifications are not available,it is also possible to estimate the bead current handling capability by measuring the resonant frequency of the filter output at low power and at maximum power.A change of resonant frequency of less than fifty percent under this condition is desirable.Examples of ferrite beads which have been tested and work well with the TPA3130D2can be seen in the TPA3130D2EVM user guide SLOU341.A high quality ceramic capacitor is also needed for the ferrite bead filter.A low ESR capacitor with good temperature and voltage characteristics will work best.Additional EMC improvements may be obtained by adding snubber networks from each of the class-D outputs to ground.Suggested values for a simple RC series snubber network would be18Ωin series with a330pF capacitor although design of the snubber network is specific to every application and must be designed taking into account the parasitic reactance of the printed circuit board as well as the audio amp.Take care to evaluate the stress on the component in the snubber network especially if the amp is running at high PVCC.Also,make sure the layout of the snubber network is tight and returns directly to the GND pins on the IC.Submit Documentation

TPA3116D2has been tested with a simple ferrite bead filter for a variety of applications including long speaker wires up to125cm and high power.The TPA3116D2EVM passes FCC class-B specifications under these conditions using twisted speaker wires.The size and type of ferrite bead can be selected to meet application requirements.Also,the filter capacitor can be increased if necessary with some impact on efficiency. There may be a few circuit instances where it is necessary to add a complete LC reconstruction filter.These circumstances might occur if there are nearby circuits which are sensitive to noise.In these cases a classic second order Butterworth filter similar to those shown in the figures below can be used.Some systems have little power supply decoupling from the AC line but are also subject to line conducted interference(LCI)regulations.These include systems powered by"wall warts"and"power bricks."In these cases,LC reconstruction filters can be the lowest cost means to pass LCI mon mode chokes using low frequency ferrite material can also be effective at preventing line conducted interference.4- 8W W4- 8W WTPA3116D2,TPA3118D2,TPA3130D2SLOS708G–APRIL2012–REVISED DECEMBER2017Submit Documentation FeedbackFigure35.TPA31xxD2Output Filters7.3.16AM Avoidance EMI ReductionTo reduce interference in the AM radio band,the TPA3116D2has the ability to change the switching frequency via AM<2:0>pins.The recommended frequencies are listed in Table6.The fundamental frequency and its second harmonic straddle the AM radio band listed.This eliminates the tones that can be present due to the switching frequency being demodulated by the AM radio.Table6.AM FrequenciesUS EUROPEANSWITCHING FREQUENCY(kHz)AM2AM1AM0 AM FREQUENCY(kHz)AM FREQUENCY(kHz)522-540540-917540-914500001917-1125914-1122600(or400)0100001125-13751122-13735000011375-15471373-1548600(or400)010000 1547-17001548-1701600(or500)010001TPA3116D2,TPA3118D2,TPA3130D2 SLOS708G–APRIL2012–REVISED DECEMBER2017Submit Documentation Feedback。

Modulation SchemeThe traditional class-D modulation scheme,which is used in the TPA032D0x family,has a differential output where each output is 180degrees out of phase and changes from ground to the supply voltage,V CC .Therefore,the differential prefiltered output varies between positive and negative V CC ,where filtered 50%duty cycle yields 0V across the load.The traditional class-D modulation scheme with voltage and current waveforms is shown in Figure 25.Note that even at an average of 0V across the load (50%duty cycle),the current to the load is high,causing high loss and thus causing a high supply current.Figure 25.Traditional Class-D Modulation Scheme's Output Voltage and Current Waveforms into anInductive Load With No InputTPA3101D2Modulation SchemeThe TPA3101D2uses a modulation scheme that still has each output switching from 0to the supply voltage.However,OUTP and OUTN are now in phase with each other with no input.The duty cycle of OUTP is greater than 50%and OUTN is less than 50%for positive output voltages.The duty cycle of OUTP is less than 50%and OUTN is greater than 50%for negative output voltages.The voltage across the load sits at 0V throughout most of the switching period,greatly reducing the switching current,which reduces any I 2R losses in the load.-12 VCurrentDifferentialVoltage Across Load-12 VCurrentDifferentialVoltage Across LoadFigure 26.The TPA3101D2Output Voltage and Current Waveforms Into an Inductive LoadEfficiency:LC Filter Required With the Traditional Class-D Modulation SchemeThe main reason that the traditional class-D amplifier needs an output filter is that the switching waveform results in maximum current flow.This causes more loss in the load,which causes lower efficiency.The ripple current is large for the traditional modulation scheme,because the ripple current is proportional to voltage multiplied by the time at that voltage.The differential voltage swing is 2x V CC ,and the time at each voltage is half the period for the traditional modulation scheme.An ideal LC filter is needed to store the ripple current from each half cycle for the next half cycle,while any resistance causes power dissipation.The speaker is both resistive and reactive,whereas an LC filter is almost purely reactive.The TPA3101D2modulation scheme has little loss in the load without a filter because the pulses are short and the change in voltage is V CC instead of 2x V CC .As the output power increases,the pulses widen,making the ripple current larger.Ripple current could be filtered with an LC filter for increased efficiency,but for most applications the filter is not needed.An LC filter with a cutoff frequency less than the class-D switching frequency allows the switching current to flow through the filter instead of the load.The filter has less resistance but higher impedance at the switching frequency than the speaker,which results in less power dissipation,therefore increasing efficiency.When to Use an Output Filter for EMI SuppressionDesign the TPA3101D2without the filter if the traces from amplifier to speaker are short (<10cm).Powered speakers,where the speaker is in the same enclosure as the amplifier,is a typical application for class-D without a filter.Most applications require a ferrite bead filter.The ferrite filter reduces EMI around1MHz and higher(FCC and CE only test radiated emissions greater than30MHz).When selecting a ferrite bead,choose one with high impedance at high frequencies,but low impedance at low frequencies.Use an LC output filter if there are low frequency(<1MHz)EMI-sensitive circuits and/or there are long wires from the amplifier to the speaker.When both an LC filter and a ferrite bead filter are used,the LC filter should be placed as close as possible to the IC followed by the ferrite bead filter.Figure27.Typical LC Output Filter,Cutoff Frequency of28kHz,Speaker Impedance=8ΩFigure28.Typical LC Output Filter,Cutoff Frequency

radiated emissions test with 21inch speaker wires.Quasi-peak measurements were taken for the 4standard test configurations,and the TPA3101D2EVM passed with at least 14-dB margin.A plot of the peak measurement for the horizontal rear configuration is shown in Figure 30.Figure 30.Radiated Emissions Prescan 30MHz -1000MHzInductors used in LC filters must be chosen carefully.A significant change in inductance at the peak output current of the TPA3101D2will cause increased distortion.The change of inductance at currents up to the peak output current must be less than 0.1m H per amp to avoid this.Also note that smaller inductors than 33m H may cause an increase in distortion above what is shown in preceding graphs of THD versus frequency and output power.Capacitors used in LC filters must also be chosen carefully.A significant change in capacitance at the peak output voltage of the TPA3101D2will cause increased distortion.LC filter capacitors should have DC-voltage ratings of at least twice the peak application voltage (the power supply voltage)and should be made of X5R or better material.In all cases,avoid using capacitors with loose temperature ratings like Y5V.TPA3101D2Closest

at 10%THD+N Figure 32.8-kHz Sine Output at 10%THD+NThe Texas Instruments patent-pending adaptive dynamic range control (ADRC)technology removes the notch inherent in class-D audio power amplifiers when they come out of clipping.This effect is more severe at higher frequencies as shown in Figure 32.Gain setting via GAIN0and GAIN1inputsThe gain of the TPA3101D2is set by two input terminals,GAIN0and GAIN1.The gains listed in Table 2are realized by changing the taps on the input resistors and feedback resistors inside the amplifier.This causes the input impedance (Z I )to be dependent on the gain setting.The actual gain settings are controlled by ratios of resistors,so the gain variation from part-to-part is small.However,the input impedance from part-to-part at the same gain may shift by ±20%due to shifts in the actual resistance of the input resistors.For design purposes,the input network (discussed in the next section)should be designed assuming an input impedance of 12.8k Ω,which is the absolute minimum input impedance of the TPA3101D2.At the lower gain settings,the input impedance could increase as high as 38.4k ΩTable 2.Gain SettingINPUT IMPEDANCE AMPLIFIER GAIN (dB)(k Ω)GAIN1GAIN0TYP TYP 002032012616103216113616INPUT RESISTANCEChanging the gain setting can vary the input resistance of the amplifier from its smallest value,16k Ω±20%,to the largest value,32k Ω±20%.As a result,if a single capacitor is used in the input high-pass filter,the -3dB or cutoff frequency may change when changing gain steps.Input Signalf =12Z C pi if= c12Z Cpi i-3 dBf cC=i12Z f pi cThe-3-dB frequency can be calculated using e the Z I values given in Table2.(1) INPUT CAPACITOR,C IIn the typical application,an input capacitor(C I)is required to allow the amplifier to bias the input signal to the proper dc level for optimum operation.In this case,C I and the input impedance of the amplifier(Z I)form a high-pass filter with the corner frequency determined in Equation2.(2) The value of C I is important,as it directly affects the bass(low-frequency)performance of the circuit.Consider the example where Z I is20kΩand the specification calls for a flat bass response down to20Hz.Equation2is reconfigured as Equation3.(3) In this example,C I is0.4µF;so,one would likely choose a value of0.47m F as this value is commonly used.If the gain is known and is constant,use Z I from Table2to calculate C I.A further consideration for this capacitor is the leakage path from the input source through the input network(C I)and the feedback network to the load.This leakage current creates a dc offset voltage at the input to the amplifier that reduces useful headroom,especially in high gain applications.For this reason,a low-leakage tantalum or ceramic capacitor is the best choice.When polarized capacitors are used,the positive side of the capacitor should face the amplifier input in most applications as the dc level there is held at2V,which is likely higher than the source dc level.Note that it is important to confirm the capacitor polarity in the application.Additionally,lead-free solder can create dc offset voltages and it is important to ensure that boards are cleaned properly.Power Supply Decoupling,C SThe TPA3101D2is a high-performance CMOS audio amplifier that requires adequate power supply decoupling to ensure that the output total harmonic distortion(THD)is as low as possible.Power supply decoupling also prevents oscillations for long lead lengths between the amplifier and the speaker.The optimum decoupling is achieved by using two capacitors of different types that target different types of noise on the power supply leads. For higher frequency transients,spikes,or digital hash on the line,a good low equivalent-series-resistance(ESR) ceramic capacitor,typically0.1m F to1µF placed as close as possible to the device V CC lead works best.For filtering lower frequency noise signals,a larger aluminum electrolytic capacitor of220m F or greater placed near the audio power amplifier is recommended.The220m F capacitor also serves as local storage capacitor for supplying current during large signal transients on the amplifier outputs.The PVCC terminals provide the power to the output transistors,so a220µF or larger capacitor should be placed on each PVCC terminal.A10µF capacitor on the AVCC terminal is adequate.。
