Abstract
A system and corresponding method is provided for digitally controlling the volume of an audio signal having a series of arithmetic units configured with combinatorial logic to operate in response to control signals to produce a digital output signal amplified in a predetermined manner to digitally control the volume.
Claims10
A system for digital control of audio volume comprising a series of arithmetic units configured with combinatorial logic and configured to operate in response to control signals to produce a digital output signal amplified in a predetermined manner to digitally control the volume.
A system configured to digitally control the amplification of a signal comprising:
- a series of arithmetic units configured to receive individual control signals corresponding to a predetermined level of volume;
- and
- a corresponding series of adjustment circuits each configured to adjust the signal in response to a control signal.
A system configured to digitally control the amplification of a signal comprising:
- a series of arithmetic units configured to receive individual control signals corresponding to a desired level of volume;
- and
- a corresponding series of adjustment circuits each configured with logic components to adjust a component of the signal in response to a control signal.
