Audio/Video to UHF TV Signal Converter (Modulator)


Posted on Feb 7, 2014

This is the circuit diagram of audio/video modulator. The circuit will convert an audio and video signal into a UHF TV signal. It`s desired to connect a video signal originating from a camera or other video source to a normal TV set. The audio and video signal is converted into a UHF TV signal so that the signal can be received through the TV ante
