Monochrome Tv Transmitter Block Diagram With Explanation. Monochrome tv receiver. The rf amplifier stage is then coupled into the mixer stage.
Synchronizing pulses are transmitted to keep the camera and the picture tube beams in step. Colour and monochrome transmitters are mostly the same circuitry. The block diagram can be broadly divided into two separate section viz one that generates an electronic signal called video signal corresponding to the actual picture and then uses this video signal to modulate an r f carrier so as to be applied to the transmitting antenna for transmission other that generates an electronic signal called audio signal containing sound information and then uses this.
First stage is located in camera housing to increase weak signal voltage to such a level as to be transmitted over a coaxial cable to the succeeding.
The basic television broadcast transmitter block diagram is shown in figure a. The rf amplifier stage is then coupled into the mixer stage. The functional block diagram can be broadly divided into two sections viz. The luminance signal from the camera is amplified and synchronizing pulses added before feeding it to the modulating amplifier.
