本文用实例介绍说明什么是振荡电路
Oscillator circuit, also known as waveform generator, there is no signal input, while the signal output signal generator, the general election by the amplifier circuit and the oscillation frequency of circuit, with transistors and operational amplifier circuit. 振荡电路也叫波形发生器，是没有信号输入，而有信号输出的信号产生器，一般由放大电路和振荡选频电路组成，有三极管和运算放大电路。选频电路一般由电阻，电容组成，即RC振荡选频电路，或者由电感电容组成，即LC振荡电路，由这个电路决定产生信号的频率较小。
