Preemphasis network

In telecommunication, a preemphasis network is a network inserted in a system in order to increase the magnitude of one range of frequencies with respect to another.

Note: Preemphasis is usually employed in FM or phase modulation transmitters to equalize the modulating signal drive power in terms of deviation ratio[?]. The receiver demodulation process includes a reciprocal network, called a deemphasis[?] network, to restore the original signal power distribution.
