| Abstract: | This paper introduces a kind of CATV charge system based on addressing control of single-chip computer. It emphasizes on 2FSK modem of locking phase loop frequency mixing, hardware and software of addressing control of single-chip computer-AT89C51. The method of switch of high frequency TV signal with PIN transistor,and the method of resistancing interference are introduced too. |
