[hpsdr] Polyphase filters

[Steve Doyle]

Hi,

This weeks teamspeak peaked my interest when when someone mentioned the potential of polyphase filters as the solution to multiple receivers, I think someone mentioned 100 separate receivers !

Anyway I came across the following tutorial, the math is beyond me but the matlab program doesn't look to bad.
