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
