THEORY:
A Monochrome Television Receiver Consists of the following functional sections which will be studied and explained as:
1. Input from Antennas:
Strongest signal is induced in the antenna if it has same polarization as the transmitting antenna. All TV antennas are mounted in horizontal position for better reception and favorable signal to noise ratio. A yogi antenna, i.e. a dipole with one reflector and two or more directors, is a compact high gain directional array, and is often used in fringe areas. In areas where signal strength is very low, booster amplifiers with suitable matching network are used. on the other hand,
