| Video Discription | When the amplitude of high frequency carrier wave is changed in accordance with the intensity of the signal, the process is called amplitude modulation. In the amplitude modulation, only the amplitude of the carrier wave is changed. The frequency and the phase of the carrier wave remains constant. animation shows the principle of amplitude modulation. First visual shows the audio electrical signal of frequency fs. Second visual shows a carrier wave of constant amplitude with frequency fc. Third one is the amplitude modulated wave. It is to be noted that the amplitudes of both positive and negative half cycles of carrier wave are changed in accordance with the signal. Thus the amplitude of the modulated wave possesses the frequency of the audio signal wave. [fGf_ng7qljI] |
