为了说明线性电路的技术动向,有必要首先弄清什么是线性电路及它所包括的内容。电子电路,可以大致区分为模拟电路和数字电路两大类。模拟电路是处理声音、图象等连续的模拟量的信息。数字电路是处理“O”“1”两个值的数字信息。如我们经常看到的无线电收音机、电视机,就是模拟电路的例子。本质上是处理对称信息的声音,除了量是连续变化的以外,还有信号电平是微小的,频率成份是从直流到高频,放大的信号应有高的功率特征。对于模拟电路所包括的内容可以分为如下三类:
In order to illustrate the technical trends of linear circuits, it is necessary to first find out what is a linear circuit and what it contains. Electronic circuits, can be broadly divided into two categories of analog circuits and digital circuits. Analog circuit is the processing of sound, images and other continuous analog information. Digital circuits are digital messages that process two values “O” “1”. As we often see the radio, TV, is an example of analog circuits. In essence, the sound of symmetric information is processed. In addition to the continuous change of signal volume, the signal level is small, the frequency component is from DC to high frequency, and the amplified signal should have high power characteristics. The contents of the analog circuit can be divided into the following three categories:
