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

Variables:

- 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.

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