I think a Cyclone IV would probably work. The resources required depend on your ADC bit-width and the stop-band rejection you need to achieve, since that determines the multiplier bit-width.

I am using a 12-bit ADC. Also, given I would need around 44 multipliers would you suggest using something like the ep4ce15 (
http://www.altera.com/literature/hb/cyclone-iv/cyiv-51001.pdf) (56 multipliers). These FPGAs are >$20 :eek:. I am hoping to use an FPGA around the $10 mark. It looks like I may need to use wider transition bands for filtering if I want an FPGA around this price.
Cheers,
