Enter the square wave period (s) into the Square Wave Frequency Calculator. The calculator will evaluate the Square Wave Frequency. 

Square Wave Frequency Formula

The following two example problems outline the steps and information needed to calculate the Square Wave Frequency.

fsq = 1 / Tsq


  • fsq is the Square Wave Frequency (hz)
  • Tsq is the square wave period (s) 

To calculate the square wave frequency, divide 1 by the square wave period.

How to Calculate Square Wave Frequency?

The following steps outline how to calculate the Square Wave Frequency.

  1. First, determine the square wave period (s). 
  2. Next, gather the formula from above = fsq = 1 / Tsq.
  3. Finally, calculate the Square Wave Frequency.
  4. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

square wave period (s) = .25

fsq = 1 / Tsq = ?
