Abstract

Multi-segment gain control system. Apparatus is provided for a multi-segment gain control. The apparatus includes logic to convert a gain control signal to an exponential signal, and logic to map the exponential signal to multiple control signals that are used to control multiple gain stages to produce linear multi-segment gain control.

Claims (21)

1. Apparatus for providing a multi-segment gain control, the apparatus comprising:

logic to convert a gain control signal to an exponential signal; and

logic to map the exponential signal to generate a first control signal and a second control signal; said first control signal and said second control signal provided to independently control a first gain segment and a second gain segment to produce multi-segment gain control; wherein said multi-segment control follows a predefined square law gain characteristic.

2. Apparatus for providing a multi-segment gain control, the apparatus comprising:

logic to convert a gain control signal to an exponential signal; and

logic to map the exponential signal to generate a first control signal and a second control signal; said first control signal and said second control signal provided to independently control a first gain segment and a second gain segment to produce multi-segment gain control; wherein said multi-segment control follows a predefined square-root law gain characteristic.

3. Apparatus for providing a multi-segment gain control, the apparatus comprising:

logic to convert a gain control signal to an exponential signal; and

logic to map the exponential signal to generate a first control signal and a second control signal; said first control signal and said second control signal provided to independently control a first gain segment and a second gain segment to produce multi-segment gain control; wherein said multi-segment control follows a predefined cubic law gain characteristic.

4. Apparatus for providing multi-segment gain control in a communications device, the apparatus comprising:

logic to generate a gain control signal from a control signal, said logic to generate a gain control signal comprising logic to generate an exponential signal; and

logic to map the gain control signal to generate a plurality of gain segment control signals;

wherein ones of the gain segment control signals are provided to independently control ones of a plurality of gain control segments to provide a predefined gain characteristic, and wherein said predefined gain characteristic is a square law gain characteristic.

5. Apparatus for providing multi-segment gain control in a communications device, the apparatus comprising:

logic to generate a gain control signal from a control signal, said logic to generate a gain control signal comprising logic to generate an exponential signal; and

logic to map the gain control signal to generate a plurality of gain segment control signals;

wherein ones of the gain segment control signals are provided to independently control ones of a plurality of gain control segments to provide a predefined gain characteristic, and wherein said predefined gain characteristic is a square root law characteristic.

6. Apparatus for providing multi-segment gain control in a communications device, the apparatus comprising:

logic to generate a gain control signal from a control signal said logic to generate a gain control signal comprising logic to generate an exponential signal; and

logic to map the gain control signal to generate a plurality of gain segment control signals;

wherein ones of the gain segment control signals are provided to independently control ones of a plurality of gain control segments to provide a predefined gain characteristic, and wherein said predefined gain characteristic is a cubic law gain characteristic.
