On the Nature of Granulation Noise in Uniform Quantization Systems

Document Thumbnail

The results of several investigations into the behavior of uniformly quantized signals are collected and discussed. In particular, the characteristics of digitized low-level signals are considered that lead to the effect known in the audio vernacular as granulation noise, an undesirable correlation between the input signal and the quantization noise components. Although the paper is primarily expository in nature, practical effects and some new simulation results are also presented.
