| May 4, 2021 at 2:36 | comment | added | Abundance | Thanks for the response. My goal is forward prediction, to be able to identify the location of a future peak in bandpassed filter from 8 to 13 Hz (alpha frequencies in the brain). So, extremely fine resolution in terms of adjacent frequencies is not necessary, just an ability to run an FIR filter without any significant artifacts, edge effects, while capturing the shape of the underlying signal (where a peak is). | |
| May 4, 2021 at 0:41 | comment | added | TimWescott | It's complicated. You should probably tell us what you're really doing. To see an 8Hz signal -- yes 125ms will do. But if you want to discriminate an 8Hz signal from an 8.1Hz signal, then by the usual methods you need at least 10 seconds. For 8.000Hz vs. 8.001, 1000 seconds. OTOH, if you absolutely positively know that there's only an 8.000Hz and an 8.001Hz signal in there, and you're measuring with absolutely positively zero noise, then in theory (some insanely impractical theory) you could get by with four or five samples at 2000Hz. | |
