I'm trying to band-pass filter data collected at 20000 Hz.  I'm unclear what the frequency units should be for the BandpassFilter function.  Are they in Hz?  Suppose I want to band-pass filter between 30 Hz and 80 Hz a signal digitized at 20000 Hz.  What would the input to BandpassFilter look like?  Thank you.
