WebJun 5, 2024 · Amplitude modulation is a type of carrier modulation used in TV pictures, radio broadcasting facsimile transmission, etc. The bandwidth of amplitude modulation is 10KHz. The overmodulation occurs when the modulating signal voltage is greater than the carrier voltage. The frequency range of amplitude modulation is between 540-1600Hz. WebAt 100% modulation (, the power efficiency of AM is 33.33%, that is, the total power carried by the sidebands is 1/3 of the total power.The middle graph shows the modulated carrier , where is the message signal and is the modulation factor. For simplicity, the amplitude of the carrier signal and the amplitude of the message signal are both kept equal to 1.
