T V Transmitter Block Diagram With Explanation. The luminance sampling rate is 143 mhz and the chroma sampling rate is 715 mhz. The basic television broadcast transmitter block diagram is shown in figure a.
Video and audio modulators and transmitting antenna production of. Chroma signal c is extracted from ccvs signal with the help of bandpass filters and amplifiers in stages bpa i and bpa ii. They only provide general information and cannot be used to repair or examine a circuit.
In this block diagram the microphone is used as the source of the audio signal but it may be another audio source also.
Transmitter block diagram transmitter block diagram etc. Video and audio modulators and transmitting antenna production of. The amplified signal is then applied to the mixer stage. Microcontroller block this block is constructed with a microcontroller like pic 8051 avr and arm depending on the requirement for controlling the application.
