I have data recorded at 1000Hz and other physio data recorded, somehow, at 1960.8 Hz (510 microsecond samples). Ideally, I would like to be able to downsample the 1960.8 hz signal to line up with the 1000Hz signal. Any suggestions? I am familiar with matlab or Python.

    $\begingroup$ Why not just use Matlab's resample command (or Python's equivalent)? You will lose all signals above 500 Hz, though. $\endgroup$

You can use the resample command mentioned as follows to accomplish this:

y=resample(x,1250,2541); % x is the input signal

  • $\begingroup$ Thanks for the response. That worked, except I changed the argument to: resample(x,1250,2451) $\endgroup$
