Abstract
A current optimal gain can be calculated directly from an effective value of an input signal by increasing the speed of the initial response without using a feedback loop, in a manner such that a mean power of the input signal and the square-root of the mean power are calculated as an inverse of the effective value, and the input signal is multiplied by the product of this inverse of the number and predetermined effective value.
