The difference between frequency modulation and phase modulation is that with frequency modulation the angular frequency of the signal is modified while with the phase modulation, the phase angle of the signal is modified.

How Phase modulation and frequency modulation are inseparable?
both are related because phase is an integral function of frequency
What are the two types of angle modulation?
Frequency Modulation and Phase Modulation
In which Analog to analog modulation methods does the peak amplitude?
Frequency modulation Phase modulation
Why frequency modulation and phase modulation are called angle modulation?
i dont know ans. of this.
In which analog-to-analog modulation methods does the peak amplitude of the carrier signal remain unchanged?
Frequency modulation and Phase modulation
How phase lock loop is used as a universal detector for Amplitude Modulation?
I could certainly be wrong, but my recollection is that a phase locked loopis a universal detector for Frequency and Phase modulation, and is quiteinsensitive to Amplitude modulation.
Which cellular system uses the most bandwidth efficient modulation?
I think it is Frequency Modulation with Phase modulation which it the most bandwidth efficient
What are the advantages and disadvantages of RC phase shift oscillator?
Advantages: it improves frequency stability. phase modulation n demodulation is easy as compared to frequency modulation.
Which modulator can perform amplitude frequency and phase modulation?
ETW-5000
Why phase modulation is used?
Actually phase modulation was used for the color signal in all analog TV systems.Phase modulation, with some signal preprocessing, was used to indirectly get frequency modulation in many FM transmitters.Certain modems use phase amplitude modulation.etc.

What are the advantages and disadvantages of phase modulation?
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. Doppler information 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. Visit my website http://harshit.org
