Frequency of PWM Solution

Follow our step by step solution on how to calculate Frequency of PWM?

FIRST Step Consider the formula

f PWM = \frac{1}{T on + T off}

Next Step Substitute values of Variables

∴

f PWM = \frac{1}{3500ms + 1251ms}

Next Step Convert Units

∴

f PWM = \frac{1}{3.5s + 1.251s}

Next Step Prepare to Evaluate

∴

f PWM = \frac{1}{3.5 + 1.251}

Next Step Evaluate

∴

f PWM = 0.210482003788676Hz

LAST Step Rounding Answer

∴

f PWM = 0.2105Hz

How to Evaluate Frequency of PWM?

Frequency of PWM evaluator uses Frequency of PWM = 1/(ON Time+OFF Time) to evaluate 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 f_PWM symbol.

How to evaluate Frequency of PWM using this online evaluator? To use this online evaluator for Frequency of PWM, enter ON Time (T_on) & OFF Time (T_off) and hit the calculate button.

FAQs on Frequency of PWM

What is the formula to find Frequency of PWM?

The formula of Frequency of PWM is expressed as Frequency of PWM = 1/(ON Time+OFF Time). Here is an example- 0.210526 = 1/(3.5+1.251).

How to calculate Frequency of PWM?

With ON Time (T_on) & OFF Time (T_off) we can find Frequency of PWM using the formula - Frequency of PWM = 1/(ON Time+OFF Time).

Can the Frequency of PWM be negative?

No, the Frequency of PWM, measured in Frequency cannot be negative.

Which unit is used to measure Frequency of PWM?

Frequency of PWM is usually measured using the Hertz[Hz] for Frequency. Petahertz[Hz], Terahertz[Hz], Gigahertz[Hz] are the few other units in which Frequency of PWM can be measured.
