Question

Advantage and disadvantages of phase modulation

Answer 1

advantages and disadvantages of phase modulation. Advantage – 1. ... we need frequency multiplier to increase phase modulation index. broadcasts are a lower bandwidth and amplitude noise comes through.

Answer 2

 


Advantage –1. Phase modulation & demodulation is easy compared to Frequency modulation.2. Phase modulator is used in determining velocity of moving target by extracting Doppler information. Dopplerinformation needs stable carrier which is possible in phase modulation but not in frequency modulation.Disadvantage –1. Phase ambiguity comes if we exceed its modulation index pi radian(180 degree).2. we need frequency multiplier to increase phase modulation index.
