Abstract :
The consequences of dithering on nonlinear quantizers are analyzed. A model of the nonlinear quantizer is considered, and a model of the same quantizer with dither is proposed. The proposed model permits the description of both monotonic and nonmonotonic nonlinear quantizer characteristics. By means of this approach, relationships are given for the total quantization error in the case of discrete binary, uniform, and Gaussian dither signals
