ABSTRACT:
A coding system for data compression and decompression of a digitized source signal, for example in accordance with the MPEG audio standard, includes an analysis filter in which an inverse discrete cosine transform operation is employed during data encoding, and a synthesis filter in which a discrete cosine transform is performed during data decoding.
