Hello,
I am trying to compare 2 EEG signals (both are 2048 long) that have the same sinusoid in them but hidden with noise. I am trying to find where this sinusoid of length 500 is. Any ideas will be appreciated.

Thanks,
Raphel
 

You will need an auto correlation filter in both directions, ignoring amplitude and phase. This can "manually" be done with an FFT and a shape comparison in the frequency domain, which is most appropriate for hardware implementation.
