Frequency of PWM Solution

STEP 0: Pre-Calculation Summary
Formula Used
Frequency of PWm = 1/(ON Time+OFF Time)
FPWM = 1/(TON+TOFF)
This formula uses 3 Variables
Variables Used
Frequency of PWm - (Measured in Hertz) - Frequency of PWM is calculated 1/Total time period.
ON Time - (Measured in Second) - ON time is time for which PWM pulse is high.
OFF Time - (Measured in Second) - OFF Time is time for which PWM pulse is low.
STEP 1: Convert Input(s) to Base Unit
ON Time: 3.5 Second --> 3.5 Second No Conversion Required
OFF Time: 1.25 Second --> 1.25 Second No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
FPWM = 1/(TON+TOFF) --> 1/(3.5+1.25)
Evaluating ... ...
FPWM = 0.210526315789474
STEP 3: Convert Result to Output's Unit
0.210526315789474 Hertz --> No Conversion Required
FINAL ANSWER
0.210526315789474 Hertz <-- Frequency of PWm
(Calculation completed in 00.000 seconds)

difference between the duty cycle and the frequency of a PWM signal

The frequency of a PWM signal describes how often the signal switches between high and low voltages. Frequency is expressed in the unit of Hertz. The duty cycle is the percentage of time the signal stays at a high voltage. It is expressed as the percentage of the period.

How to Calculate Frequency of PWM?

Frequency of PWM calculator uses Frequency of PWm = 1/(ON Time+OFF Time) to calculate the Frequency of PWm, The frequency of PWM signal describes how often the signal switches between high and low voltages. Frequency is expressed in the unit of Hertz. Frequency of PWm is denoted by FPWM symbol.

How to calculate Frequency of PWM using this online calculator? To use this online calculator for Frequency of PWM, enter ON Time (TON) & OFF Time (TOFF) and hit the calculate button. Here is how the Frequency of PWM calculation can be explained with given input values -> 0.210526 = 1/(3.5+1.25).

FAQ

What is Frequency of PWM?
The frequency of PWM signal describes how often the signal switches between high and low voltages. Frequency is expressed in the unit of Hertz and is represented as FPWM = 1/(TON+TOFF) or Frequency of PWm = 1/(ON Time+OFF Time). ON time is time for which PWM pulse is high & OFF Time is time for which PWM pulse is low.
How to calculate Frequency of PWM?
The frequency of PWM signal describes how often the signal switches between high and low voltages. Frequency is expressed in the unit of Hertz is calculated using Frequency of PWm = 1/(ON Time+OFF Time). To calculate Frequency of PWM, you need ON Time (TON) & OFF Time (TOFF). With our tool, you need to enter the respective value for ON Time & OFF Time and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
