1. A method for quantizing an input signal using a predictive delta-sigma modulator, comprising: quantizing said input signal using a quantizer; determining a quantization error associated with said quantizer by subtracting an input to said quantizer from an output of said quantizer; measuring a correlation coefficient between said quantization error and an input to said quantizer; reducing said measured correlation by subtracting a multiple of said input to said quantizer from said quantization error, wherein said multiple is based on said correlation coefficient; generating an error prediction value using an error predictive filter; and subtracting said error prediction value from said input signal.
