| Abstract: | The design scheme of a new CATV signal multiple demodulator is introduced. The demodulator has two main parts, hardware and software. It can perform channel selection and signal demodulating using it's own keyboard or the PC connected. It can separate the radio signal imported by a CATV cable into video signals and audio signals of 16 TV channels without distortion. Cooperating with video capture cards and relevant software,it can real-time monitor the signals of 16 TV channels simultaneously in a PC. |
