There’s also a stopband of 500 Hz to 1000 Hz. Since the sample rate is 2 kHz, it doesn’t make sense to go past half of that. The “desired #taps” box should already say “minimum” and ...
That sheet uses the FIR filter technique we talked about before. The filter has a passband from 0 Hz to 60 Hz and the stopband starts at 100 Hz. You can see a partial gain vs frequency plot.
