T V Transmitter Block Diagram With Explanation. The carrier wave is then amplified by the radio frequency RF power amplifier to the desired output wattage. The functional block diagram can be broadly divided into two sections viz.
There are two input stages one for AF and one for VF. 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. This bit information sequences will modulate the carrier frequency and the phase of the carrier frequency will shifted as function of binary information.
The RF oscillator generates the carrier signal.
By using the block diagram in Figure above if we generate the binary number randomly we will get the information sequences. Synchronizing pulses are transmitted to keep the camera and the picture tube beams in step. These are digitized by AD converters. Block Diagrams Tutorial - Block Diagrams - AM.
