Difference between Frequency and Phase Modulation

Comparison and Difference between FM and PM

1. In frequency modulation FM, the max frequency deviation depends on amplitude of modulating signal and its frequency. In phase modulation PM, the max phase deviation depends on amplitude of modulating signal.

2. In frequency modulation FM, frequency of the carrier is modulated by modulating signal. In phase modulation PM, phase of the carrier is modulated by modulating signal.

3. In FM, modulation index is increased as modulation frequency is reduced and vice versa. In PM, modulation index remains same if modulating signal frequency is change.
