What is modulation and demodulation ? |
|
Answer» Solution :Modulation. The process by which some characteristics of a relatively high frequency wave ( CALLED carrier wave ) is varied in ACCORDANCE with the instantaneous value of a low frequency wave ( called modulating wave ) is called modulation. Demodulation : Process of detection or demodulation is the inverse of modulation. During Demodulation, audio signal is separated from modulated signal and FED to the speaker or head-phone which REPRODUCES the original sound.
