摘要
分析了用运算放大器组成正弦波振荡电路的起振条件和输出电压幅值的调节及选频网络的构成。由此引伸到用运算放大器组成的信号发生器的实际应用。
This paper is involved in the analysis of oscillation starting condition, output voltage amplitude adjustment, and frequency selection network composition of sinu soidal coave oscillation circuit. Togcther, they maxe up the operational amplifier. Furthermore, signal generator which consists of operational amplifier is applied. The function and characteristics of stable amplitude circuit are anuylysed in details.
