State two factors by which the range of TV signal can be increased??
Range of a TV signal can mean two different things.
- Area of the reach of the signal transmitted by a tower.
- Ways to increase the range of the area covered by a tower: The range (d) of a tower of height (h) is given by d = √(2Rh), where R = radius of earth and thus a constant quantity. Hence range can be increased by increasing the tower height.
- Bandwidth. Bandwidth is the difference between the highest and lowest band frequency. This in turn can be increased by digitilisation of the transmission process and improved multiplexing etc.
