Phase Comparators - an overview | ScienceDirect Topics
https://www.sciencedirect.com/topics/engineering/phase-comparators
The phase comparator output signal is formed by a signal rich in harmonics. This signal is the result of the comparison of the reference signal v e and signal v S provided by the output of the VCO. The signal at the phase comparator output also contains a slowly varying component that is retrieved at the output of the low-pass filter.

Comparators are used in many common applications, and Class-D amplifiers were mentioned above. A comparator has the incoming audio applied to one input, and a triangle wave on the other. The output is a rectangular waveform, with the mark-space (on-off) ratio varying depending on the audio input signal.

Phase comparison technique is the most widely used technique for all practical directional, distance, differential and carrier relays. In a phase comparator, the operation of the relay takes place when the phase relation between two inputs S 1 and S 2 varies within certain specified limits. Both inputs must exist for an output to occur; ideally, operation is independent of their …

The signal v r located at the phase comparator output is a periodic signal. Its frequency is twice the frequency of the signal v e or that of signal v s. The phase shift between signals v e and v S is equal to ΔΦ. The phase shift ΔΦ is proportional to Δt. ΔΦ = Δt T 2 π.

The phase detector is based around two D type flip flops and an NAND gate, although there are a number of slightly different variants. The circuit for the dual D-type phase comparator operates by comparing the reference and VCO signals which enter the clock inputs, one on each D-type.

Essentially, phase refers to sound waves — or simply put, the vibration of air. When we listen to sound, what we’re hearing are changes in air pressure. Just like the ripple of a stone in water, sound is created by the movement of air. And just as in water, those movements cause a rippling effect — waves comprised of peaks and troughs.

AD630 as a phase comparator for amplitude-varying signals. Looking for guidance in applying AD630 as a phase comparator for detected signals whose amplitude is not fixed. My understanding is that the AD630's output dc level indicates both amplitude and phase difference. I need just phase difference. I'm certainly willing to consider other devices.
