WebbIARE, Best Engineering College Webb3Fig: Typical pre-emphasis circuit. De-emphasis: • To avoid amplitude and phase distortion we have to artificially decrease the amplitude of FM signal on receiver side. This concept is known as de-emphasis. • De-emphasis circuit consists of integrator which will reduce amplitude of FM signal by slope -20dB/decade.
