摘要

本文对SWFM和等宽PFM脉冲序列作了频谱分析

导出了傅里叶级数表达式

对几种PFM方案进行了比较

指出:倍频式PFM方案兼有SWFM和等宽PFM两种方案的优点

是中短距离光纤彩色电视传输中较理想的一种方案。

Abstract

Spectral properties of SWFM and equivalent-width PFM pulse trains are analysed.Fourier series expressions of the two pulse trains are deduced. Compared with several PFM plans

PFM plan of double frequency mode has the advantages of both SWFM and the equivalent-width PFM plans

thereby

it is a good transmision plan for optical colour TV transmission of short and medium distances.
