Dec 16, 2012 · what is the duration (sec) of your original signal? FFT converts sec to 1/2pi or rad/sec units. Then QRS complexes were detected and each complex In case of EDF files, all signals can be imported as a Matlab structure or particular signals can be selected from a drop-down list. In order to convert it to Hz you need to multiply by 2*pi.
