Quantization errors in averaged digitized data

Analytic expressions which describe average quantization errors in digitize d data with additive noise are derived. The magnitude of this error depends on the noise present in the analog signal, the bin-size (the difference be tween neighboring quantization levels) and also the signal itself. An itera tive process, which corrects for these residual quantization errors after a veraging, is proposed and tested in simulations. Alternatively a method for avoiding quantization errors during digitization of signals which will lat er be averaged is suggested. (C) 2001 Elsevier Science B.V. All rights rese rved.
