Modulation is required for the following reasons: to transmit signal over an antenna through free space, to improve signal to noise ratio and to make the low frequency signals travel long distances. Modulation is required for all of the above.
Answer: Modulation is required for to transmit signal over an antenna through free space, to improve signal to noise ratio and to make the low frequency signals travel long distance.
Modulation is process of varying one or more properties of a periodic waveform. Modulation is necessary because it can ensure Reduction in the height of antenna and avoids mixing of signals.
Summary:
