Enter the signal-to-noise ratio of the output and the signal-to-noise ratio of the input into the Calculator. The calculator will evaluate the Array Gain.

## Array Gain Formula

AG = SNRo/ SNRi

Variables:

- AG is the Array Gain ()
- SNRo is the signal-to-noise ratio of the output
- SNRi is the signal-to-noise ratio of the input

To calculate Array Gain, divide the signal-to-noise ratio of the output by the SNR of the input.

## How to Calculate Array Gain?

The following steps outline how to calculate the Array Gain.

- First, determine the signal-to-noise ratio of the output.
- Next, determine the signal-to-noise ratio of the input.
- Next, gather the formula from above = AG = SNRo/ SNRi.
- Finally, calculate the Array Gain.
- 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.

signal-to-noise ratio of the output = 6.5

signal-to-noise ratio of the input = 7
