From phase frequency
Phase comparison is a comparison of the phase of two waveforms, usually of the same nominal frequency. In time and frequency, the purpose of a phase comparison is generally to determine the frequency offset (difference between signal cycles) with respect to a reference. A phase comparison can be made by … See more In physics and mathematics, the phase of a periodic function $${\displaystyle F}$$ of some real variable $${\displaystyle t}$$ (such as time) is an angle-like quantity representing the fraction of the cycle covered up to See more Let $${\displaystyle F}$$ be a periodic signal (that is, a function of one real variable), and $${\displaystyle T}$$ be its period (that is, the smallest positive real number such … See more The phase of an oscillation or signal refers to a sinusoidal function such as the following: where $${\displaystyle \textstyle A}$$, $${\displaystyle \textstyle f}$$, and • It … See more • "What is a phase?".
