Form Factor & Crest Factor Formula and Calculator

This calculator determines the form factor and crest factor of AC signals using the following formulas:

• Form Factor (FF) = RMS Value / Average Value
• Crest Factor (CF) = Peak Value / RMS Value

Where:

• RMS Value is the root mean square value of the signal.
• Average Value is the average value of the signal over one complete cycle.
• Peak Value is the maximum value of the signal.

Form and Crest Factor Calculator

Example Calculation: Let’s say we have an AC signal with the following values and asked to calculate the form factor and crest factor.

Inputs:

• RMS Value = 10 V
• Average Value = 7 V
• Peak Value = 14 V

Outputs:

• Form Factor (FF) ≈ 1.43
• Crest Factor (CF) = 1.4

This means that the form factor of the signal is approximately 1.43, indicating the relationship between the RMS and average values, while the crest factor is 1.4, indicating the ratio of the peak value to the RMS value of the signal. The form factor and crest factor are important parameters in analyzing the characteristics of AC signals, especially in power electronics and signal processing applications.
