Abstract
A method in a signal processor for quantizing a digital signal is provided. A fixed-point approximation of a value X÷Q is generated, wherein X is a fixed-point value based on one or more samples in the digital signal, and wherein Q is a fixed-point quantization parameter. A correction is generated, and the approximation is modified with the correction.
