The point of the high-pass filter is to drop out the low-frequency parts of the signal where the drift is found - i.e., since there should be no overall change in the signal over the course of a minute, any frequency component below ~1/60 Hz can (in theory) be ignored as drift. | |
| Mar 3, 2023 at 15:14 | comment | added | Blindman67 | This makes no sense. How does reducing the signal gain when below a cutoff (0.3Hz) correct the signals frequency? If the signal drifts too far you will get no signal above the noise. Are you sure you stated the questions title correctly? | |
