The entire 1228 data points correspond to one cycle of the signal

You do realize that your file was a 1D array and not a 2D array, right?

But that was not the problem. The problem was that fs was too low.

Have a look at the images below and the code snippet.

El problema estaba relacionado con FS con un valor que era demasiado bajo.
Tiene que ser fs / 2> = fh, donde FH = 400, por lo que fs tiene que ser> 200.
