SAA2003中文资料飞利浦数据手册PDF规格书

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.
