1． 掌握压控振荡器的基本原理和调试方法。
二． 实验原理
压控振荡器，顾名思义，其输出频率随输入电压的改变而变化。它大致可分为两类，一类是调谐式，另一类是多谐式。多谐式一般线性好，但输出不是正弦波，只能通过间接方式获得。振荡频率一般较低。调谐式多用于发射机中，一般高频电子线性课程会有介绍。
这里介绍两种压控振荡器及其常用电路类型，供大家参考
-1. VCO master the basic principles and debugging methods. 2. VCO experimental principle, as the name implies, the output frequency with the input voltage changes and changes. It can be broadly divided into two categories : one is tuning, and the other is more harmonic. More generally linear harmonic good, but not sine wave output, and only through indirect manner. The generally low frequency oscillation. Multi-tuner for transmitters, the general linear high-frequency electronic curriculum will be introduced. Here introduces two voltage-controlled oscillator circuit and the type commonly used for reference
