Quantization Grid, Split from Topic ID #55966 Options

[KMD]

I have thought that this phenomana may be real for years . I call it the "quantiztion grid". An analog waveform can change direction or cross the zero line at an infinite number of locations. Sampling and Quantization create a grid to which features of the waveform are statistically constrained. Increasing the sample rate at a fixed bandwidth inreases the quantization grid density. Whether it is perceivable is what is in question. This experiment may have proved it. I will give some thought to a simillar experiment that forum members can do for themselves and start a new topic on it.

Yes, noise (thermal, shot, interference, etc.) that causes the signal to deviate from one of the discrete quantization levels as opposed to quantization error which is the reason that the signal is clamping to one of the discrete quantization levels.

Other than that the operative is "most" and how much is dependent on the highest frequency present in the signal.
