deo (Vttko) and an audio signal (Audio )} another component is a signal modulator (radio modulation device), it may sound, - video signal is modulated onto a TV channel by the television viewing additional channel program. Opponents audio and video input port of the TV, you can not shoot adjuster, directly connected to the sound tuner, video output. Circuit shown in Figure 1-41, S-band for the death choice. RP thrown in selection. 7812 three-terminal regulator generates + 12V voltage supply respectively high frequency head and demodulator shot.
