Abstract

A multi-quantizer coding/decoding apparatus and method, which quantizes and dequantizes input signals by respectively using multiple quantizers and dequantizers having different quantization bits, so as to generate multiple compression codes and multiple dequantization signals. And the present invention uses a data selection controller to determine an optimized compression code and dequantization signal according to a step value of a step adaptor.
