Crest Factor Solution

STEP 0: Pre-Calculation Summary

Formula Used

Crest Factor = Peak Value of Signal/RMS Value of Signal
CF = X_peak/X_rms
This formula uses 3 Variables

Variables Used

Crest Factor - The Crest Factor of an AC current waveform is the ratio of waveform's peak value to its RMS value.
Peak Value of Signal - (Measured in Volt) - Peak Value of Signal is the maximum value attained by an alternating quantity during one cycle. It is also known as the maximum value or crest value.
RMS Value of Signal - (Measured in Volt) - RMS Value of Signal is the root-mean-square value of a signal. For a digitized signal, it represents the average "power" of a signal.

STEP 1: Convert Input(s) to Base Unit

Peak Value of Signal: 90 Volt --> 90 Volt No Conversion Required
RMS Value of Signal: 23 Volt --> 23 Volt No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

CF = X_peak/X_rms --> 90/23

Evaluating ... ...

CF = 3.91304347826087

STEP 3: Convert Result to Output's Unit

3.91304347826087 --> No Conversion Required

FINAL ANSWER

3.91304347826087 ≈ 3.913043 <-- Crest Factor

Crest Factor = Peak Value of Signal/RMS Value of Signal
CF = X_peak/X_rms

What is significance of Crest Factor?

The crest factor provides information about the peakiness or spikiness of a signal. A higher crest factor indicates a waveform with sharp peaks, while a lower crest factor indicates a more evenly distributed energy across the waveform.

How to Calculate Crest Factor?

Crest Factor calculator uses Crest Factor = Peak Value of Signal/RMS Value of Signal to calculate the Crest Factor, Crest Factor is the ratio of the peak voltage value that an average reading or root-mean-square voltmeter will accept without overloading to the full-scale value of the range being used for measurement. Crest Factor is denoted by CF symbol.

How to calculate Crest Factor using this online calculator? To use this online calculator for Crest Factor, enter Peak Value of Signal (X_peak) & RMS Value of Signal (X_rms) and hit the calculate button. Here is how the Crest Factor calculation can be explained with given input values -> 3.913043 = 90/23.

FAQ

What is Crest Factor?

Crest Factor is the ratio of the peak voltage value that an average reading or root-mean-square voltmeter will accept without overloading to the full-scale value of the range being used for measurement and is represented as CF = X_peak/X_rms or Crest Factor = Peak Value of Signal/RMS Value of Signal. Peak Value of Signal is the maximum value attained by an alternating quantity during one cycle. It is also known as the maximum value or crest value & RMS Value of Signal is the root-mean-square value of a signal. For a digitized signal, it represents the average "power" of a signal.

How to calculate Crest Factor?

Crest Factor is the ratio of the peak voltage value that an average reading or root-mean-square voltmeter will accept without overloading to the full-scale value of the range being used for measurement is calculated using Crest Factor = Peak Value of Signal/RMS Value of Signal. To calculate Crest Factor, you need Peak Value of Signal (X_peak) & RMS Value of Signal (X_rms). With our tool, you need to enter the respective value for Peak Value of Signal & RMS Value of Signal and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
