Enter the amplitude, angular frequency, and phase angle into the calculator to determine the phase difference.

Phase Difference Formula

The following formula is used to calculate the phase difference.

PD = A * sin ( ω * Φ ) 
  • Where PD is the phase difference
  • A is the amplitude of the waveform
  • ω is the angular frequency (rad/s)
  • Φ is the phase angle (rad)

To calculate the phase difference, multiply the amplitude of the waveform by the sine of the product of the angular frequency and phase angle.

Phase Difference Definition

A phase difference is defined as angle at which a waveform has shifted from some reference point along the x-axis.

Phase Difference Example

How to calculate a phase difference?

  1. First, determine the amplitude.

    Calculate the amplitude of the wave.

  2. Next, determine the angular frequency.

    Calculate the angular frequency of the wave.

What is a phase difference?

A phase difference, also known as phase shift, is the angle that a waveform has shifted from a reference point along the x-axis.

What is a phase shift?

A phase shift is the same as a phase difference.

What is a phase angle?

A phase angle is an angle representing a difference in phase. 360 degrees is one complete cycle.
