序列信号发生器,之d触发器异步复位和异步置位
在序列信号发生器中，D触发器是一种常用的元件。

它可以在时钟的控制下接受一个输入信号D，并将其延迟一个时钟周期后输出到Q端。

D触发器可以通过异步复位（Asynchronous Reset）和异步置
位（Asynchronous Set）来控制其输出。

异步复位指的是在不考虑时钟的情况下，通过一个特定的输入信号将D触发器的输出强制置为特定的状态，通常是低电平。

这个输入信号可以是一个单独的复位信号，当复位信号为高电平时，D触发器的输出被复位为低电平。

异步复位是一种强制复位的方法，它不受时钟控制。

当复位信号为低电平时，D触发器的输出会恢复到正常的工作状态。

异步置位指的是在不考虑时钟的情况下，通过一个特定的输入信号将D触发器的输出强制置为特定的状态，通常是高电平。

这个输入信号可以是一个单独的置位信号，当置位信号为高电平时，D触发器的输出被置位为高电平。

异步置位是一种强制置位的方法，它不受时钟控制。

当置位信号为低电平时，D触发器的输出会恢复到正常的工作状态。

异步复位和异步置位可以通过控制相关的输入信号来实现序列信号发生器的复位和置位功能，从而调整其输出序列或重置其状态。

信号发生器<方波）1 绪论1.1 设计背景数字信号处理器，也称DSP芯片，是针对数字信号处理需要而设计的一种具有特殊结构的微处理器，它是现代电子技术、相结合的产物。

一门主流技术，随着信息处理技术的飞速发展，计算机技术和数字信号处理技术数字信号处理技术逐渐发展成为它在电子信息、通信、软件无线电、自动控制、仪表技术、信息家电等高科技领域得到了越来越广泛的应用。

数字信号处理因为运算速度快，具有可编程特性和接口灵活的特点，使得它在许多电子产品的研制、开发和应用中，发挥着重要的作用。

采用DSP芯片来实现数字信号处理系统是当前发展的趋势。

1.2设计目的1．通过课程设计加深对DSP软件有关知识的学习与应用。

2．学习汇编语言并能熟练掌握与应用。

3．了解定时中断原理。

1.3设计任务1. 设计一个信号发生器<方波）。

2. 在XF引脚上输出任意频率的方波。

2 设计原理及分析2.1设计原理作为本设计的核心器件，DSP芯片的运算能力要求比较高，同时又存在运算过程中大量数据交换的特点。

方波信号发生器是信号中最常见的一种，它能输出一个幅度可调、频率可调的方波信号，在科学研究及生产实践中均有着广泛应用。

目前，常用的信号发生器绝大部分是由模拟电路构成的，当这种模拟信号发生器用于低频信号输出往往需要的RC值很大，这样不但参数准确度难以保证，而且体积大和功耗都很大，而由数字电路构成的低频信号发生器，虽然其低频性能好但体积较大，价格较贵，而本文借助DSP运算速度高，系统集成度强的优势设计的这种信号发生器，比以前的数字式信号发生器具有速度更快，且实现更加简便。

这里说明一下使用TI公司的DSP芯片TMS320C5502<以下简称5502）来产生方波信号的原理：因为产生一个方波信号需要有一个适合的定时器来重复产生一个与方波周期相同的计数周期，并用一个比较寄存器来保持调制值，因此，比较寄存器的值应不断与定时寄存器的值相比较，这样，当两个值相匹配时，就会在响应的输出上产生一个转换<从低到高或从高到低），从而产生输出脉冲，输出的开启<或关闭）时间与被调制的数值成正比，因此，改变调制数值，相关引脚上输出的脉冲信号的宽度也将随之改变。

According to the signal waveform, the function can be divided into sine signal (waveform) signal, pulse signal and random signal generator and so on four categories. Signal generator also called source or oscillator, in production practice and science and technology has been widely used in the field. Various waveform curve can be represented with trigonometric function equation. Can produce various waveform, such as triangle wave, sawtooth wave, rectangle wave (including square wave), sine wave of the circuit is called a function signal generator.Also known as the signal generator, which is used to produce specific parameters required for the circuit being measured electric testing signal. In testing, research, or adjust the electronic circuits and devices, measurement circuit of some electric parameters, such as measuring the frequency response, noise coefficient, for voltmeter, etc, are required to conform to the conditions set by the technology of electrical signals, to simulate a used in the actual work of excitation signal of the device under test. When the requirement of system steady state characteristics of the measurement, need to use sine signal source of known amplitude and frequency. When the transient characteristics of the testing system, and to use front time, pulse width and repetition period known rectangular pulse source. And the parameters of the signal source output signal, such as frequency, waveform, the output voltage, or power, can under certain ?Working principle of the signal generatorSignal generator is used to produce frequency of 20 hz ~ 200 KHZ sine signal (low frequency). Besides has the voltage output, and power output. So the usage is very wide, can be used for testing or repair a variety of electronic instruments and equipment in the frequency characteristic of the low frequency amplifier, gain, passband, also can be used for outer modulation signal of high frequency signal generator. In addition, electronic voltmeter in calibration, it can provide ac voltage signal. Low-frequency signal generator: the principle of the system including the main vibration level, the main vibration output adjustment potentiometer, voltage amplifier, attenuator, power amplifier and output impedance converter (output transformer) and instructs the voltmeter.Main vibration level low frequency sinusoidal oscillation signals, the voltage amplifier amplification, to achieve the requirement of the output voltage amplitude, the attenuator can be directly output voltage output, with the main vibration output adjustment potentiometer to adjust the size of the output voltage.Signal generator is introducedSine signal generator: sine signal is mainly used in the measuring circuit and frequency characteristic of the system, the nonlinear distortion, gain and sensitivity, etc. According to the frequency range can be divided into low-frequency signal generator, high-frequency signal generator and the microwave signal generator; According to the output level can be adjusted the scope and degree of stability can be divided into simple signal generator (signal) and standard signal generator (attenuation to the output power can be accurately - 100 decibels below milliwatts) and power signal generator (output power up to tens of milliwatts); Way frequency change into tuner type signal generator, frequency sweep signal generator, program-controlled signal generator and frequency synthesis type signal generator, etc.Low frequency signal generator: this includes audio (200 ~ 20000 hz) and video (1 hz ~ 10 MHz) range of sine wave generator. Main vibration level generally use RC oscillator, difference frequency oscillator is also available. For ease of testing system frequency characteristic and asked for peace amplitude-frequency characteristic waveform distortion.High frequency signal generator, frequency of 100 KHZ to 30 MHZ frequency, VHF signal generator of 30 ~ 300 MHZ. General use LC tuned oscillator, frequency can be read by tuning capacitor dial scale. Main purpose is to measure all the receiver technology indicators. Output signal is available internally or with the low-frequency sine amplitude modulation or frequency modulation signal, the output frequency voltage can decay to microvolt under 1.The output signal level can accurate readings, adjustable amplitude or frequency can also be used for electricity meter reading. In addition, the instrument and to prevent leakage signal of good shielding.Standard signal generatorMicrowave signal generator: from decimeter wave to millimeter wave band of the signal generator. Signal is usually by uhf triode with distribution parameters of the resonator and the reflex klystron, but has gradually be microwave transistor, field effect tube and gunn diode solid-state devices to replace the trend. Instrumentsgenerally rely on mechanical tuning cavity to change frequency, each covering one octave, signal power is general by cavity coupling can be up to 10 milliwatts. Simple signal source requires only can add 1000 HeFang wave amplitude modulation, while standard signal generator will output a benchmark level adjustment to one milliwatt, again from the back with the attenuator db milliwatts of the readout signal value; Must also have internal or with rectangular pulse amplitude modulation, in order to test the radar receiver.Frequency sweep and program-controlled signal generator, frequency sweep signal generator can produce constant amplitude, frequency, in limited within the scope of linear change signal. In hf and VHF frequency scanning voltage or current control oscillation circuit components (such as a varactor tube or core coil) to implement the frequency sweep oscillator; In microwave paragraph early use voltage tuning frequency sweep, use change the backward wave pipe spiral electrode of the dc voltage to change the oscillation frequency, then widely used magnetic tuning frequency sweep, YIG ferrite ball for microwave solid oscillator tuning circuit, by scanning current control dc magnetic field changes the resonance frequency of the ball. Frequency sweep signal generator with automatic sweep, hand control, process control and remote control, etc.Frequency synthesis type signal generator: this signal generator is not produced by the oscillator directly, but rather serve as standard frequency source with high stability crystal oscillator, frequency synthesis technology is used to form the arbitrary frequency of the signal, is the same as the standard frequency source frequency accuracy and stability. Output signal frequency according to decimal Numbers often go, highest can reach 11 digital high resolution. Frequency except by manual selection can also be programmed control and remote control, also can be carried out step magnitude frequency sweep, is suitable for automatic test system. Direct frequency synthesizer by addition, multiplication, crystal oscillator, filter and amplification circuit, frequency transformation rapidly but complicated circuits, high output frequency can reach around 1000 MHZ. Use morer indirect frequency .Function generator, also called waveform generator. It can produce certain cyclical time function waveform (mainly sine wave, square wave, triangle wave, sawtooth wave and pulse wave, etc.). Frequency range can be from a few hz JiWei hz ultra-low frequency until even tens of megahertz. Except for communications, instrumentation and automatic control system test, also widely used in othernon-electric measurement field. One method of figure 2 to generate the waveform, the integral circuit and a certain threshold switching circuit with hysteresis characteristics, such as Schmitt trigger is connected into a loop, integrator can square integral into triangle wave. Schmitt circuit and can make a triangle wave rises to a certain threshold or fall into another threshold jump to form a square wave, frequency division can along with the integrator of the RC value of the variable .Pulse signal generator: width, amplitude and repetition frequency adjustable rectangular pulse generator, can be used to test the transient response of linear systems, or use the analog signal to test the radar, road and other performance of the pulse number system. Pulse generator is mainly composed of master oscillator, delay, pulse forming stage, output stage and attenuator etc. Master oscillator circuit for harmonic oscillator, usually in addition to outside the self-excited oscillation, the main work according to the trigger mode. Usually after additional trigger signal output a front-facing first trigger pulse, in order to trigger the oscilloscope observation instrument, in advance and then after a period of delay time is adjustable to output the signal pulse, the width can be adjusted. Some can output pairs of main pulse, ?Random signal generator: random noise signal generator and the pseudo random signal generator can be divided into two kinds of signal generator.Noise signal generator: completely random signal is within the working frequency band with uniform white noise spectrum. Commonly used white noise generator are: working at 1000 MHz saturated diode type of coaxial system under white noise generator; Microwave gas discharge tube waveguide system used in white noise generator; Using the noise of the crystal diode reverse current solid-state (can work under 18 GHz) across the spectrum, etc. The intensity of the noise generator output must be known, usually with the output noise power over the resistor thermal noise decibels (referred to as the s/n ratio) or by their noise temperature. With white noise as input signals, for example, and measure the output of the network signal and the input signal of the cross-correlation function, you can get the impulse response function of the networkSignal generator applicationsSignal generator also called source or oscillator, in production practice and science and technology has been widely used in the field. Various waveform curve can be represented with trigonometric function equation. Can produce various waveform, such as triangle wave, sawtooth wave, rectangle wave (including squarewave), sine wave of the circuit is called a function signal generator.Function signal generator in circuit experiment and test equipment has the very wide range of USES. In communications, broadcasting and television system, for example, require rf (radio frequency), the radio frequency wave is the carrier, the audio frequency (low frequency), to carry out or pulse signal, video signal needs to be able to produce high-frequency oscillator.In industry, agriculture, biomedical and other fields, such as the high frequency induction heating, melting, quenching, ultrasonic diagnosis, nuclear magnetic resonance (NMR) imaging, etc., all need power or big or small, frequency or high or low of the oscillator.信号发生器信号发生器是指产生所需参数的电测试信号的仪器。
