ABSTRACT:
An electronic dB-to-linear gain conversion system (10). The system comprises an input (12) for receiving a gain index signal (GI) representing a desired dB value. The desired dB value is selected from a set having an integer number S of dB values. The system also comprises a storage circuit (16) for storing an integer number V of linear gain values and circuitry for producing a linear gain signal (LG) in response to the gain index signal and to one of the V linear gain values. In the preferred embodiment, V is less than S.
