I could certainly be wrong, but my recollection is that a phase locked loop
is a universal detector for Frequency and Phase modulation, and is quite
insensitive to Amplitude modulation.

How does quadrature amplitude modulation works?
QAM is a combination of phase modulation & amplitude modulation.
In which Analog to analog modulation methods does the peak amplitude?
Frequency modulation Phase modulation
In which analog-to-analog modulation methods does the peak amplitude of the carrier signal remain unchanged?
Frequency modulation and Phase modulation
Which modulator can perform amplitude frequency and phase modulation?
ETW-5000
How is signal recoverability improved in quadrature amplitude modulation?
by maximizing the measurable differences between shifts in phase and amplitude
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.

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
Why amplitude modulation is used for video transmission?
IF we use frequency modulation for transmitting video signal this can cause phase shifting .and eyes can percieve this distortion effect easly . and requires more bandwidth to send the signal .Color levels are adjusted by amplitude in TV .So it s more logic to use Amplitude modulation .
In phase modulation the amount of phase shift in the carrier signal depends on the of the modulating signal and the rate of phase shift depends on the of the modulating signal?
Amplitude Frequency
How does a Michelson interferometer convert phase modulation into amplitude modulation?
initially the two beams i.e. one reflected and one transmitted from semi reflecting glass were in different phase but when they superimpose two interference take place - constructive and destructive. since in both the interferences amplitude changes.
Why normalization of message signal is necessary in conventional amplitude modulation?
to maintain the constant frequency and the phase parameters at the output
