Pre-emphasis is used in FM transmissions to boost the higher frequency spectrum of the audio modulating signal. This is reversed through de-emphasis in the FM receiver. This is done to reduce noise level that would otherwise be present in the audio signal due to the triangular spectral distribution of noise in FM.

This concept is known as de-emphasis. • De-emphasis circuit consists of integrator which will reduce amplitude of FM signal by slope -20dB/decade.
