What is difference between phase shift and phase difference?

In other words phase shift is the lateral difference between two or more waveforms along a common axis and sinusoidal waveforms of the same frequency can have a phase difference.

What is phase shifting?

Techopedia Explains Phase Shift

Phase shift simply means that the two signals are at different points of their cycle at a given time. Phase shift is measured as the angle (in degrees or radians) between two points on a circle at the same time, demonstrating the progress of each wave through its cycle.

What is phase difference?

The phase difference is the difference in the phase angle of the two waves. Path difference is the difference in the path traversed by the two waves. The relation between phase difference and path difference is direct. They are directly proportional to each other.

Is phase shift the same as time shift?

The phase shift from the all-pass filter is similar to a simple time delay, but not exactly the same. Time delay shifts all frequencies by the same amount of time, whereas phase shift delays some frequencies longer than others.
