Hello,
I have a band limited signal. It was obtained for ultrasound imaging purpose. I want to know the center frequency of the signal. But looking at the spectrum plotted by MATLAB fft, it is not possible to determine the center frequency of the signal, because at the central region the band there are too many peaks. Also, the spectrum within the band is not smooth at all. How can I determine the center frequency of the signal.?
