Question

Give the bandwidth of a TV signal for transmission.

Answer 1

Hint: TV signals contain both voice and video signals to broadcast so it avoids disruption we need higher wavelength radio waves.

Complete step by step solution:
In general, different kinds of media use different bandwidths of transmission channels to broadcast their message so that it should not interfere with other EM signals broadcasted simultaneously from different stations.
A typical TV signal or video signal to be transmitted require 4-5 MHz of Bandwidth. But with added sound into it, the resulting TV signal has 6 MHz of bandwidth.

There is a vast and complex procedure of deciding the size of the bandwidth and operational bandwidth for transmission. In general, the prime factor assumes a loss of signal quality and minimum cost on infrastructure making. All these are enforced using radio waves for transmission on a low scale. There are other means of transmission as well. It includes skywave propagation, radio waves propagation, microwave propagation, etc. The selection of one of the mediums is dependent on the requirements we have and the range of the signal. Here, everywhere we talk of signals. But what does it mean? The signal is something that can be transmitted from one end to another end and carry information or data into it.

$\therefore$ A typical TV signal or video signal to be transmitted require 4-5 MHz of Bandwidth.

Note:
Bandwidth is the range of frequencies that are required to transmit a given signal efficiently with the least distortion in the actual signal. It depends on various factors like transmission media and the type of signal to transmit.
