Digital Signal Processing Technology For R-DAT

As one of consumer audio equipment, the CD (Compact Disc) player has come into wide use since its commercialization of 1982 for its high quality sound, easy operation and low price. The Direct Broadcasting Satellite (DBS) service has started in Japan in 1984. On the other hand, the Digital Audio Tape recorder (DAT) which has both recording and reproducing function and easy recording from these digitalized audio sources, is expected to be a next-generation audio product.
