1. An electronic dB-to-linear gain conversion system, comprising:
an input for receiving a gain index signal representing a desired dB value, wherein the desired dB value is selected from
a set having an integer number S of dB values;
a storage circuit for storing an integer number V of linear gain values; and
circuitry for producing a linear gain signal in response to the gain index signal and to one of the V linear gain values;
and wherein V is less than S.
