Statistical theory of quantization
Bernard Carlos Widrow, István Kollár, Ming-Chang Liu · IEEE Transactions on Instrumentation and Measurement · 1996
The effect of uniform quantization can often be modeled by an additive noise that is uniformly distributed, uncorrelated with the input signal, and has a white spectrum. This paper surveys the theory behind this model, and discusses the conditions of its validity. The application of the model to floating-point quantization is demonstrated.
