What's the big deal? I just spent the last two years of my life consulting
on a project to do a REAL-TIME 12.5MHz 32-bit complex FFT, up to 2 million
points. Is that enough?? We've built about ten of them so far, and more
to come... I don't know if you can quite afford the $250,000 price tag, but
hey! You asked! Regards...
