This program for Scilab searches for primary peaks in the segments of brainwave signal spectrum which are much above the signal spectrum average.
Brainwave segments of 1 s are Fourier transformed, thresholded and merged if contiguous.
Selected segments are drawn in time domain, frequency domain and a narrow-band analysis at 75 Hz is attempted.
This program should detect strong external signals in brainwave recordings. Weak signals are not detected.
This program requires the "edf2ascii"...
