GENERAL DESCRIPTION

The SAA2003 performs the sub-band filtering and audio

frame codec functions in the Precision Adaptive Sub-band

Coding (PASC) system. It can be used as a stand-alone

decoder for playback only applications, but requires the

addition of an Adaptive Allocation and Scale Factor

processor (SAA2013) in order to perform PASC encoding

in a DCC record system.
