What do you mean by the term modulation? And where it is employed?
Expert
Modulation is the method of varying some features of a periodic wave with external signals.
Radio communication superimposes this information bearing signal to the carrier signal.
These high frequency carrier signals can be transmitted over the air simply and are capable of the travelling long distances.
The features (that is, amplitude, frequency or phase) of the carrier signal are varied in accordance with information bearing the signal.
Modulation is employed to send information bearing the signal over long distances.
