How to Calculate Closed Loop Gain?
Closed Loop Gain calculator uses Gain with Feedback = 1/Feedback Factor to calculate the Gain with Feedback, The Closed Loop Gain formula is defined as the gain that results when we apply negative feedback to "tame" the open-loop gain. The closed-loop gain can be calculated if we know the open-loop gain and the amount of feedback (what fraction of the output voltage is negatively fed back to the input). Gain with Feedback is denoted by A_{f} symbol.
How to calculate Closed Loop Gain using this online calculator? To use this online calculator for Closed Loop Gain, enter Feedback Factor (β) and hit the calculate button. Here is how the Closed Loop Gain calculation can be explained with given input values -> 0.25 = 1/4.
