I have digitized FM radio hiss using a $10 transistor radio feeding into the LINE in of my soundcard. The spectrum looks poisson with prominant, periodically spaced noise spikes. It does not pass Diehard.
Yeah, I ran Diehard on it .. and that is why I wanted to find some references on removing bias.
But if you take the PARITY of 8 bits to get one bit, then assemble bytes out of these bits, the results pass Diehard.
This is a neat idea. I smiled when I read this in RFC1750
1. There are some nice spectrogramming shareware programs out there.
I haven't been able to find any for UNIX/X .. any recommendations for Win31 (I'll try it with Wabi ;) software? [source clipped] :) Sweet. Thanks. Michael J.
