Unit 1 Electronics:Analog and Digital 1.As with series resonance, the greater the resistance in the circuit the lower the Q and, accordingly, the flatter and broader the resonance curve of either line current or circuit impedance. 对于串联谐振,电路中的电阻愈大Q值就愈低,相应地线路电流或电路阻抗的谐振曲线也就愈平、愈宽。 2.A wire carrying a current looks exactly the same and weighs exactly the same as it does when it is not carrying a current. 一根带电的导线其外表与重量都与不带电导线完全一样。 3.Click mouse on the waveform and drag it to change the pulse repetition rate, or directly enter a new value of the period in the provided dialogue box, while keeping the pulse width unchanged. 在波形上点击鼠标并拖动来改变脉冲重复频率,或者在提供的对话框中直接输入新的周期值,而保持脉冲宽度不变。 4.Electronics is the science and the technology of the passage of charged particles in a gas, in a vacuum, or in a semiconductor. Please note that particle motion confined within a metal only is not considered electronics. 电子学是一门有关带电粒子在气体、真空或半导体中运动的科学技术。注意,在本书中粒子运动仅限于金属的情况不属于电子学。 5.Hardware technologies have played vital roles in our ability to use electronic properties to process information, but software and data processing aspects have not developed at the same speed. 硬件技术在我们使用电子特性来处理信息的能力中一直起着重要作用,而软件及数字处理方面却没能与硬件同步发展。 6.However, in a properly designed DC amplifier the effect of transistor parameter variation, other than Ico, may be practically eliminated if the operation point of each stage is adjusted so that it remains in the linear operation range of the transistor as temperature varies. 然而在设计得当的直流放大器中,若调节每一级的工作点使之在温度变化时保持在晶体管线性区,就能在实际上消除Ico以外的晶体管参数变化所造成的影响。

A tran sistor is made of a solid piece of a semic on ductor material , with at least three term in als for connection to an exter nal circuit. A voltage or curre nt applied to one pair of the tran sistor ' s term in als cha nges the curre nt flow ing through ano ther pair of term in als. Because the con trolled curre nt can be much larger tha n the con trolli ng curre nt, the tran sistor provides amplificati on of a sig nal. The tran sistor is the fun dame ntal buildi ng block of moder n electro nic devices, and is used in radio, telepho ne, computer and other electr onic systems. Some tran sistors are packaged in dividually but most are found in in tegrated circuits. 在电子技术中,晶体管是一种,常用来放大或进行开关控制电子信号的半导体器。晶体管是 由一块固体半导体材料制成的,且至少有三个终端与外部电路连接。电压或电流适用于一双 晶体管的终端改变目前流经的另一对终端。因为受控电流可以远大于控制电流,晶体管提供 信号的放大。晶体管是构建现代电子设备的基本单元,并在收音机,电话,计算机和其它电子系统被使用。一些晶体管被单独包装,但大多数都在集成电路中。 Tran sformer A transformer is a device that transfers electrical energy from one circuit to anther through in ductively coupled electrical con ductors . A cha nging curre nt in the first circuit creates a cha nging magn etic field; in turn, this magn etic field in duces a cha nging voltage in the sec ond circuit. By add ing a load to the sec on dary circuit, one can make curre nt flow in the tran sformer, thus tran sferri ng en ergy from one circuit to the other. 变压器是一种通过感应耦合将电能从一个电路传输到另一个电路的装置。在第一电路中的一 个变化的电流创建一个不断变化的磁场;反过来,这个磁场诱导第二个电路中的电压变化。 通过向二次回路中增加负载,使电流在变压器中流动,从而将能量从一个电路传递到另一个 电路中。 Relay A relay is an electrical switch that ope ns and closes un der the con trol of ano ther electrical circuit . In the origi nal form ,the switch is operated by an electromag net to ope n or close one or many sets of con tacts. It was inven ted by Joseph Henry in 1835. Because a relay is able to con trol an output circuit of higher power tha n the in put circuit ,it can be con sidered to be, in a broad sen se, a form of an electrical amplifier. 继电器是一种电子开关,控制另一个电路的打开和关闭。在原始形式中,该开关是由一个电磁铁操作,打开或关闭一个或多个触点。它是由约瑟夫亨利在1835年发明的。由于继电器 能够控制比输入电路功率更高的输出电路,广义上说,它可以被认为是电子放大器的一种形 式。 Types of circuits In any circuit where the on ly oppositi on to the flow of electr ons is resista nee , there is a defi nite relati on

基本电路 包括电路模型的元素被称为理想的电路元件。一个理想的电路元件是一个实际的电气元件的数学模型,就像一个电池或一个灯泡。重要的是为理想电路元件在电路模型用来表示实际的电气元件的行为可接受程度的准确性。电路分析,本单位的重点,这些工具,然后应用电路。电路分析基础上的数学方法,是用来预测行为的电路模型和其理想的电路元件。一个所期望的行为之间的比较,从设计规范,和预测的行为,形成电路分析,可能会导致电路模型的改进和理想的电路元件。一旦期望和预测的行为是一致的,可以构建物理原型。 物理原型是一个实际的电气系统,修建从实际电器元件。测量技术是用来确定实际的物理系统,定量的行为。实际的行为相比,从设计规范的行为,从电路分析预测的行为。比较可能会导致在物理样机,电路模型,或两者的改进。最终,这个反复的过程,模型,组件和系统的不断完善,可能会产生较准确地符合设计规范的设计,从而满足需要。 从这样的描述,它是明确的,在设计过程中,电路分析中起着一个非常重要的作用。由于电路分析应用电路模型,执业的工程师尝试使用成熟的电路模型,使设计满足在第一次迭代的设计规范。在这个单元,我们使用20至100年已测试通过机型,你可以认为他们是成熟的。能力模型与实际电力系统理想的电路元件,使电路理论的工程师非常有用的。 说理想电路元件的互连可用于定量预测系统的行为,意味着我们可以用数学方程描述的互连。对于数学方程是有用的,我们必须写他们在衡量的数量方面。在电路的情况下,这些数量是电压和电流。电路分析的研究,包括了解其电压和电流和理解上的电压施加的限制,目前互连的理想元素的每一个理想的电路元件的行为电路分析基础上的电压和电流的变量。电压是每单位电荷,电荷分离所造成的断电和SI单位伏V = DW / DQ。电流是电荷的流动速度和具有的安培SI单位(I= DQ/ DT)。理想的基本电路元件是两个终端组成部分,不能细分,也可以在其终端电压和电流的数学描述。被动签署公约涉及元素,当电流通过元素的参考方向是整个元素的参考电压降的方向端子的电压和电流的表达式使用一个积极的迹象。 功率是单位时间内的能量和平等的端电压和电流的乘积;瓦SI单位。权力的代数符号解释如下: 如果P> 0,电源被传递到电路或电路元件。 如果p<0,权力正在从电路或电路元件中提取。 在这一章中介绍的电路元素是电压源,电流源和电阻器。理想电压源保持一个规定的电压,不论当前的设备。理想电流源保持规定的电流不管了整个设备的电压。电压和电流源是独立的,也就是说,不是任何其他电路的电流或电压的影响;或依赖,就是由一些电路中的电流或电压。一个电阻制约了它的电压和电流成正比彼此。有关的比例常数电压和一个电阻值称为其电阻和欧姆测量。 欧姆定律建立相称的电压和电流的电阻。具体来说,V = IR电阻的电流流动,如果在它两端的电压下降,或V=_IR方向,如果在该电阻的电流流是在它两端的电压上升方向。 通过结合对权力的方程,P = VI,欧姆定律,我们可以判断一个电阻吸收的功率:P = I2R= U2/ R 电路节点和封闭路径。节点是一个点,两个或两个以上的电路元件加入。当只有两个元素连接,形成一个节点,他们表示将在系列。一个闭合的路径是通过连接元件追溯到一个循环,起点和终点在同一节点,只有一次每遇到中间节点。 电路是说,要解决时,两端的电压,并在每个元素的电流已经确定。欧姆定律是一个重要的方程,得出这样的解决方案。 在简单的电路结构,欧姆定律是足以解决两端的电压,目前在每一个元素。然而,对于更复杂的互连,我们需要使用两个更为重要的代数关系,被称为基尔霍夫定律,来解决所有的电压和电流。 基尔霍夫电流定律是: 在电路中的任何一个节点电流的代数和等于零。 基尔霍夫电压定律是: 电路中的任何封闭路径上的电压的代数和等于零。 1.2电路分析技术 到目前为止,我们已经分析应用结合欧姆定律基尔霍夫定律电阻电路相对简单。所有的电路,我们可以使用这种方法,但因为他们而变得结构更为复杂,涉及到越来越多的元素,这种直接的方法很快成为累赘。在这一课中,我们介绍两个电路分析的强大的技术援助:在复杂的电路结构的分析节点电压的方法,并网电流的方

1.This electron beam sweeps across each line at a uniform rate,then flies back to scan another line directly below the previous one and so on,until the horizontal lines into which it is desired to break or split the picture have been scanned in the desired sequence. 电子束以均匀的速率扫描每一行,然后飞速返回去扫描下一行,直到把被扫描的图像按所希望的顺序分割成行。 2.The technical possibilities could well exist,therefore,of nation-wide integrated transmission network of high capacity,controlled by computers,interconnected globally by satellite and submarine cable,providing speedy and reliable communications throughout the word 因此,在技术上完全可能实现全国性的集成发送网络。这种网络容量大,由计算机控制,并能通过卫星和海底电缆实现全球互联,提供世界范围的高速、可靠的通信。 3.Transit time is the primary factor which limits the ability of a transistor to operate at high frequency. 渡越时间是限制晶体管高频工作能力的主要因素 4.The intensity of sound is inversely proportional to the square of the distance measured from the source of the sound. 声强与到声源的距离的平方成反比。 5.The attenuation of the filter is nearly constant to within 0.5 dB over the entire frequency band. 该滤波器的衰减近于恒定, 整个频带内的变化在0.5 dB以内。 6.At present, the state of most semiconductor device technology is such that the device design and process technology must be supplemented by screening and inspection procedures, if ultimate device reliability is to be obtained and controlled. 目前, 大多数半导体器件的技术尚未十分完善, 以至若要获得并控制器件最终的可靠性, 就必须辅以筛选和检验, 以弥补设计和工艺技术之不足 7.Bandwidth of transistor amplifiers vary from about 250 MHz in the L band to 1000 MHz in the X band. 晶体管放大器的带宽在L波段约为250 MHz, 在X波段为1000 MHz。 8.The output of the differential amplifier is fed to the circuit’s output stage via an offset-compensation network, which causes the op-amp’s output to center at zero volts. The output stage takes the form of a complementary emitter follower, and provides a low-impedance output. 差动放大级的输出通过一个失调补偿网络与输出级相连, 目的是使运放的输出以0 V为中心。输出级采用互补的射极跟随器的形式以使输出阻抗很低 9.Because of the very high open-loop voltage gain of the op-amp, the output is driven into positive saturation (close to +V) when the sample voltage goes slightly above the reference voltage, and driven into negative saturation (close to-V) when the sample voltage goes slightly below the reference voltage. 由于运放的开环电压增益很高, 当取样电压略高于参考电压时, 输出趋向于正向饱和状态(接近+V)。当取样电压低于参考电压时, 输出趋向于负向饱和状态(接近-V)。 10.If the signal source were direct connected instead of capacitor coupled, there would be a low resistance path from the base to the negative supply line, and this would affect the circuit bias conditions. 如果信号源和电路不是用电容耦合而是直接相连,从基极到负电源线就会一个低阻通路,并且这将影响到电路偏置状态 11.The differential amplifier has a high-impedance (constant-current)“tail”to give it a high input impedance and a high degree of common-mode signal rejection. It also has a high-impedance collector (or drain) load, to give it a large amount of signal-voltage gain (typically about 100 dB). 差动放大极有一个高阻抗的“尾巴”(恒流源)以提供高输入阻抗和对共模信号的深度抑制,同时,它还具有一个高阻抗和集电极或漏极负载以提供高的信号电压增益(典型的数据是100dB). 12.On the other hand, a DC negative-logic system, as in Figure 3.6(b), is one which designates the more negative voltage state of the bit as the 1 level and the more positive as the 0 level. 另一方面, 如图3.6(b)所示, 把比特的较低的电压状态记为1电平, 较高的电压状态记为0电平, 这样的系统称为直流负逻辑系统。 13.For example, to represent the 10 numerals (0, 1, 2, …, 9) and the 26 letters of the English alphabet would require 36 different combinations of 1’s and 0’s. Since 25<36<26, then a minimum of 6 bits per bite are required in order to accommodate all the alphanumeric characters. 例如,要表示0~9十个数字和英文字母表中的26个字母,就需要0和1的36种不同的组合。因为25<36>26,
