摘要
本文是对研制八进八出视频音频选择开关中几个技术问题的总结，讨论了在多路视频音频选择开关中ＣＭＯＳ模拟开关器件的单电源应用；对多路视频信号输入时串扰问题的解决；以及一种分立元件构成的甲乙类互补输出电路．
This essay is a summation of some technical problems in researching the 8-in-and-8-out-vedio-audio switch,discussing the application of the single power of the CMOS analougue switchers in the vedio-audio multiplexing.It also offors the solution to the jam question which is caused when the multiplex vedio singals input and A-B compensated Video-out circuit made of the individual components.
