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!

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

17 taps is probably too short for the stated requirements.

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