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.

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

signal-to-noise ratio of the output = 6.5

signal-to-noise ratio of the input = 7
