Phase modultion is one of the three ways of modulating or altering a signal so that it is able to carry information. The other two are amplitude and frequency modulation. Phase modulation is used in high speed modems.
the modulation system is of FM
Frequency modulation Phase modulation
QAM is a combination of phase modulation & amplitude modulation.

Collector modulation is the amplitude modulation in which modulator varies the collector voltage of a transistor.
AM - Amplitude Modulation FM - Frequency Modulation
modulation
Frequency Modulation and Phase Modulation
frequency modulation..
due to velocity modulation density modulation occurs in TWT
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.
the modulation system is of FM
i dont know ans. of this.
Frequency modulation Phase modulation
QAM is a combination of phase modulation & amplitude modulation.
Modulation index is also called as Modulation depth. The modulation index of a modulation scheme describes by how much the modulated variable of the carrier signal varies around its unmodulated level.
