Pre emphasis is done2 pointsFor boosting of modulating signal voltageFor modulating signals at higher frequenciesIn FM before modulationAll of the above
Question
Solution 1
Pre-emphasis is done for several reasons:
Boosting of Modulating Signal Voltage: Pre-emphasis is used to increase the strength of the higher frequency components of the signal. This is done to balance the signal because the amplitude of a frequency modulated signal decreases with frequency.
