Band Pass filter output data

I don't use fir compiler, so hopefully somebody else may help better.

It looks ok to me. Though you can choose other structures e.g multipliers(instead of distributed arithmetic, at least for testing), your coefficient width need not be that high(if you wish you may go lower with little or no effect on filter response). Your output resolution need not be different from that of input.

Again make sure your sampling rate is indeed 1000Hz.
