ABSTRACT:
A division technique unified quantizer-dequantizer circuit is disclosed. The unified quantizer-dequantizer includes a division circuit receiving a half step size q and an input signal x. The division circuit outputs a quantized coefficient signal y and a remainder R, where ##EQU1## The unified quantizer-dequantizer also includes a circuit receiving the quantized coefficient signal y, the remainder R, the half step size q and the input signal x. This circuit outputs a reconstructed signal r where, ##EQU2##
