But in some cases where p/c is impossible or not wanted for some reason, irregular sampling can push the error signal below the perception threshold. Or, precisely, push the perception threshold above the error signal. | |
| Dec 16, 2021 at 9:01 | comment | added | Knut Inge | Irregular sampling is basically a method to avoid proper pre-filtering, at the cost of increased pseudo-noise, right? If Nyquist can be economically satisfied (either by lowpass filtering or by having a high sample rate), then irregular sampling seems pointless. | |
