Abstract
A signal processing apparatus for processing data digital signals is disclosed. The signal processing apparatus includes a high-efficiency power switching amplifier that optimizes processing during low-power applications. A signal equalizer is further coupled to the power switching amplifier and has a plurality of signal bands for defining equalization characteristic desired for the signal processing system. A gain control unit is coupled to the signal equalizer for adjusting gain of the equalized input signal handled by the signal equalizer. Lastly, a digital amplitude compressor is coupled to the gain controller and the power switching amplifier and is programmable so as to compress only those signals having an amplitude greater than a first threshold level without compressing those signals that fall below that first threshold level. Typically, low-power applications cover wattage ranging from two to seven watts of power.
