A distortion removal system (16) for reducing the quantization distortion that results from quantization of a signal by sample-by-sample quantization techniques is disclosed. The distortion removal system (16) uses the signal previously quantized with the sample-by-sample quantization techniques to determine an expected quantization distortion using distortion determination module (62). The expected quantization distortion is determined for each of a plurality of frames of the signal using the distortion determination module (62). The expected quantization distortion is removed from each of the frames of the signal using distortion removal module (56). |
