| Abstract: | In AV switch circuit design, multiple selecting circuit was used to choose chip CD4052BC 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. |
