how do i design a A 17-tap low-pass FIR filter with pass-band upper frequency of 6 Hz and stop-band lower frequency of 30 Hz and the sampling frequency is 512 Hz.And how can i pass my input vector through it? Any help will really be useful!

I have downloaded aami3am.mat file from physionet atm. and now i want to pass that ecg signal vector through this low pass filter. I am stuck here as I am not able to find a particular matlab command comprising of all these required parameters. Any help will really be handy. thank you!

[Christoph F.]

Filters are applied to signals using the filter(B, A, sig) function.

17 taps is probably too short for the stated requirements.

[Star Strider]

The filtfilt function is preferable to filter, since filtfilt has a maximally-flat phase response.
