Enter the voltage output and the voltage input into the Calculator. The calculator will evaluate the Gain Factor. 

Gain Factor Formula

GF = 10*LOG (Vo/Vi)^2


  • GF is the Gain Factor (dB)
  • Vo is the voltage output
  • Vi is the voltage input

How to Calculate Gain Factor?

The following steps outline how to calculate the Gain Factor.

  1. First, determine the voltage output. 
  2. Next, determine the voltage input. 
  3. Next, gather the formula from above = GF = 10*LOG (Vo/Vi)^2.
  4. Finally, calculate the Gain Factor.
  5. 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.

voltage output = 34

voltage input = 12
