图像数字化加扰系统中采样信号产生电路

A Kind of Circuit about Producing Sample Signal in the System of Image Digit Scrambling

介绍了图像数字化加扰的基本原理，讨论了图像数字化加扰系统中的采样频率的选取问题。

First,this paper reviewed the principle of AV digital scrambling,then discussed how to select sample frequency.Finally,a detail circuit of producing sample signal in AV digital scrambling was given.
