FFT on 8-bit?

Anybody know how I can write an FFT program in basic to analyze low
frequency (<30hz) signals over the paddle input?

Thanks,

Pat

If you don't get a suggestion here, try comp.dsp since that is where they
live. You may have to specify basic vs C, but I am sure there is someone
there that has done it.

BTW: Paddles are only updated at 60 Hz, so you will get more then a bit of
noise if your signal is anywhere near 30 Hz. You may need to put the pots in
their fast scan mode.

If you don't need to do it in real time, I wrote several FFT and FHT
programs some years ago, using TurboBASIC XL. You will find them
