| For example, in a radio broadcast using amplitude modulation the audio signal is transmitted as the mean amplitude of a radio-frequency carrier so demodulation requires a circuit which measures the amplitude and filters out the carrier. For example, in a radio broadcast using amplitude modulation the audio signal is transmitted as the mean amplitude of a radio-frequency carrier so demodulation requires a circuit which measures the amplitude and filters out the carrier. Conventional amplifiers are susceptible to clipping--the introduction of harmonic and intermodulation distortion, often heard as a grating harshness in the sound--when the amplitude of the audio signal exceeds the amplifier's maximum output. |
