Good info. I had to solve this problem a couple of weeks ago and ended up coding up my own solution. I had to calculate (well, estimate) the SNR of signals for which I had little useful information. So, I needed to isolate the 'signal' (my signals had only one peak) from the rest of the waveform to get an estimate for the noise. Bah, not fun.
