Does anyone knows how to use wiener filter as bandpass filter? I have a signal whose frequency is from 0 to 9 hz and i want to filter signal 0 - 0.25 Hz,0.25 - 0.5 Hz, 0.5 - 0.75 Hz and so on. If possible please post MATLAB code for the same.

To my understanding, Wiener filter and bandpass filter are two different things. The purpose of Wiener filter is to make the output of the filter look like a reference signal so it does not take signal frequency component as design parameters.
