摘要
本文提出一个存在多径传播时电视图像信号的传输模型,从该模型中可得出多径传输时的图像信号的传输函数和冲击响应,由此可以分析出电视重影波对接收图像的影响。该模型已考虑到电视机的幅频特性和目前接收机都采用的同步检波方式。
in this paper,we give a transmission model of TV picture with ghost waves. Fromthis model,we can get the transfer functions and the pulse response of TV picture transmission system with ghost waves. Then we analyse the influence of ghost waves on TV picture.In this model,the receiving frequency response of the TV set and the synchronous detectionused in normal TV set have been considered.
