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 else can I help you with?
In order to send more than one bit at a time during a single phase on a carrier modulation is used?
amplitude modulation is used
Application of signals and systems?
what is phase modulation changing of the phase depending upon the modulated signal is said to be a phase modulation
In which Analog to analog modulation methods does the peak amplitude?
Frequency modulation Phase modulation
How does quadrature amplitude modulation works?
QAM is a combination of phase modulation & amplitude modulation.
What is phase opposition disposition modulation?
For phase opposition disposition (POD) modulation all carrier waveforms above zero reference are in phase and are 180 out of phase with those below zero.
Why phase modulation is least used?

What is the difference between frequency modulation and phase modulation?
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.
What are the two types of angle modulation?
Frequency Modulation and Phase Modulation
In order to send more than one bit at a time during a single phase on a carrier modulation is used?
amplitude modulation is used
How Phase modulation and frequency modulation are inseparable?
Phase modulation and frequency modulation are related because changes in the phase of a signal result in corresponding changes in its frequency. When the phase of a signal is modulated, it causes variations in the frequency of the signal as well. Therefore, in practice, it is difficult to separate phase modulation from frequency modulation, especially in communication systems where both aspects are interconnected.

How phase lock loop is used as a universal detector for Amplitude Modulation?
A phase-locked loop (PLL) can be used as a universal detector for Amplitude Modulation (AM) by utilizing its ability to track the phase and frequency of the incoming modulated signal. The PLL locks onto the carrier frequency of the AM signal, allowing it to demodulate the envelope variations caused by the modulation. By comparing the output of the PLL with the original carrier frequency, the modulation information can be extracted as the difference between the two signals. This makes the PLL an effective detector for demodulating AM signals across a wide range of frequencies and modulation depths.
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
