Modulation and Demodulation Modulation; Is the process of combining the low-frequency signal (information / intelligence) with a very-high frequency radio waves (carrier waves) before transmission. The resulting waves is known as the modulated carrier wave, this is the wave that is finally transmitted. All this process takes place at the transmitter. Demodulation; is the opposite … Read more
