Need of pre-emphasis and de-emphasis circuits in digital communication?
de-emphasis is the complement of pre-emphasis, in the antinoise system called emphasis. Emphasis is a system process designed to decrease, (within a band of frequencies), the magnitude of some (usually higher) frequencies with respect to the magnitude of other (usually lower) frequencies in order to improve the overall signal-to-noise ratio by minimizing the adverse effects of such phenomena as attenuation differences or saturation of recording media in subsequent parts of the system.Special time constants dictate the frequency response curve, from which one can calculate the cutoff frequency.

What is the importance of De-emphasis network in FM receiver?
One characteristic of the FM process is that the noise is distributed such that it's lowest at the bottom frequency of the channel, and increases steadily as you move up the channel. Knowing this, pre- and de-emphasis is the clever trick we use to decrease the noise in the FM communications channel. Here's how it's done:At the transmitter, pre-emphasis is applied to the baseband information before modulation ... the main channel L+R and L-R signals, plus any subcarriers that the station carries. Pre-emphasis is intentional distortion of the frequency response across the baseband that attenuates the low-frequency end, and progressively amplifies everything as you move up in frequency. The result of this operation is what actually gets transmitted.The receiver is responsible for doing just the opposite. It applies de-emphasis immediately after demodulation ... it attenuates the high-frequency end of the baseband, and progressively amplifies everything as you move down in frequency.If the pre- and de- are accurately matched, then the frequency response of the system winds up flat across the baseband, which is what we want. But ... by attenuating the higher frequencies, the receiver also changes the noise-content of the baseband, from a distribution that gets worse as you move up in frequency, to a distribution that's flat across the channel.

What is pre-emphasis and de-emphasis in FM?
In FM, the effect of noise is more on higher frequencies when compared with low frequencies. Therefore in order to have high signal-to-noise ratio(low noise), the high frequencies are amplified at the transmitter side and for compensation deemphasis(decreasing the amplitude of those boosted frequencies ) is done at receiver.
