摘要
在电视机AV切换电路设计中,运用多路选择芯片CD4052BC进行多路音频的切换,通过单路视频输入和双声道音频输入协调TV信号及各路外部设备信号之间的关系,使其能正确在屏幕上显示和再现伴音,并对提高视频效果和AV切换能力的各方面因素作了详细介绍。
In AV switch circuit design, multiple selecting circuit was used to choose chip CIM052BC to switch multi audio, and through the relationship between the TV signals of single circuit video input and double sound channel input and each circuit external device signals, it can be displayed correctly on the screen and reproduce underscore. Furthermore, all the factors about how to advance the effect on video and the ability of AV switch were discussed.
