GENERALIZED NONSUBTRACTIVE DITHERING IN A/D CONVERSION – THEORY AND SIMULATION RESULTS

Tomasz Adamski

Abstract

The paper deals with mathematical fundamentals of the generalized nonsubtractive dithering method (which can be used in A/D converters and sampling systems with repetitive sampling). The new concept is based on inverting a "dithering characteristic" <i>F</i> defined in the paper for arbitrary (but fixed) quantization functions. Errors of the method are assessed and analyzed in detail.
