We have mainly researched two FM signal demodulation techniques called Frequency Spectrum Separation and PhaseLock Loop in the first part.
一次解调中研究了频谱分离法和锁相法两种实现鉴频的技术。

The phaselock loop is a feedback control system that makes two telecommunication signals' phase synchronization, suitable to the synchronous trigger circuit of the convertor device.
锁相环路是完成两个电信号相位同步的反馈控制系统,适宜于变流装置的同步触发电路之中。
