WebMay 31, 2016 · ADC performs 50/60 Hz filtering internally. I had the intention of using a filter with a cutoff frequency between 10-100 hz (not Kilohertz) to completely filter out most frequencies, but Many circuits that I have seen have simple RC anti-aliasing filters with cutoff frequencies higher than 1khz. WebJul 11, 2024 · I am wondering about choosing the sampling rate (fs) and the cutoff frequency (fc) of the Butterworth filter (one is normal and the other is a point by point mode). The figure is shown below. For the normal filter, I choose fs = 1000Hz, fc = 10Hz. For the PtbyPt filter, I choose fs = 1Hz and fc = 0.01Hz.
