How do you calculate the phase shift of a signal?

Calculating Phase Shift

The phase shift equation is ps = 360 * td / p, where ps is the phase shift in degrees, td is the time difference between waves and p is the wave period. Continuing the example, 360 * -0.001 / 0.01 gives a phase shift of -36 degrees.

How do you find the phase difference between two signals?

An oscilloscope's timing markers (Figure 1 ) offer the simplest technique to measure the phase between two signals. The time difference between two corresponding points on the signals represents the phase in units of time. Multiplying the ratio of this value to the period of the signals calculates the phase in degrees.

What is the formula which can be used for finding phase difference between two signals on CRO?

In CRO we can measure the phase difference by X-Y mode operation. At a phase shift ϕ = 0° or 360°, the pattern indicated by CRO is a diagonal straight line making 45° with the X-axis. At a phase shift of ϕ = 90°, the pattern indicated by CRO is a clockwise rotating circle.
