Are you planning feedback ? For a comparison, I did a few years ago sampling in Python, with NI cards (they ensure time accuracy which can never be achieved in software), 50 kHz (divided over 1 to 8 channels), 32 bit, storage and graphical display, and processor activity was about 10%.
Maybe you should also look at what those radio guys from gnu radio achive. cheers, Stef > As there is no switch statement in Python, I've been looking around for a > good implementation. > Most of the algorithms I've come across seem to be based on parsing > applications.
