Re: bandpass filter design for ACTEL FPGA
You need to design the filter first using some filter design software
(this will give your the filter architecture and coefficients). Then
you can worry about putting into the device. You don't say much about
your requirements or environment. Audio sample rates are much lower
than what modern FPGAs can be clocked at, so it is perfectly reasonable
to use a combination of bit serial and time-multiplexed logic to reduce
the footprint of your filter.
