[hpsdr] Polyphase filters

[Steven Doyle]

If we got it implemented in verilog on Mercury we would not be limited to 
the 192K base band per receiver but could have different receivers each with 
different base bands. So we could then have for example a receiver for each 
of the amateur bands. Googling around I have discovered some verilog 
implementations and even some IP cores are already available.

Ah too many interesting projects around !
