摘要

本文介绍了一种利用延迟线鉴频器解调出射频或微波信号的调频噪声后

使其负反馈到调相器以实现信号噪声谱改善及实时监测的新方法。给出了分析及一组获得约10dB噪声谱改善的初步实验结果。所用设备简单、可靠

方法亦有潜力

可推广应用到有关场合。

Abstract

A new method using delay line descriminator for demodulating and monitoring FM noise and degeneration loop for improving it is presented. The theoretical analysis and a set of experimental results which shows about 10 dB phase noise reduction are given. This method is simple

reliabl and potential. It can be used on various occasions.
