Expert Answer
Modulation is the process of superimposing the low audio frequency information signals or base band message signals(modulating signal) on a high frequency wave or pulse (called the carrier wave or pulse) such that some property of carrier wave is varied in accordance with the information or message signal.The resultant wave is called the modulated wave,that is transmitted.
