摘要

A quantization-precision-reproduction method including the steps of reproducing an m-bit-length high-precision component lower than or equal to quantization precision of an n-bit-length digital signal on the basis of the n-bit-length digital signal, and generating an n + m-bit-length digital signal by adding the reproduced m-bit-length high-precision component to a low-order bit of the n-bit-length digital signal is provided.
