Feb 15, 2023 · The quantization noise is corelated to the input signal, but not to its distribution. Signals can be uncorrelated and even if they have the same distribution.
When the number of quantization levels is small, the quantization noise becomes signal dependent. In an image of the noise, signal features can be discerned.
