General Composition of Sine Wave Oscillator正弦波振荡器振荡电路的常见构成

1、Amplifying circuit-realize energy control.

放大电路——实现能量控制。

2、Positive feedback network-meets the conditions for starting vibration.

正反馈网络——满足启振条件。

3、Frequency selection network-only one frequency satisfies the oscillation condition to obtain a sine wave output of a single frequency. Commonly used frequency selection networks include RC frequency selection and LC frequency selection

选频网——只有一个频率满足振荡条件才能获得单频的正弦波输出。常用的频率选择网络包括 RC 频率选择和 LC 频率选择。

4、 Amplitude stabilization link-makes the circuit easy to start and oscillate stably, with little waveform distortion.

稳幅环节——使电路易于启动，振荡稳定，波形失真小。
