Find the Principle Frequencies

Hello,
I have taken a noisy signal, and used fft, followed by in turn, ifft to remove the noise from said signal. I am also interested in locating the value of the Primary Frequencies in Hz. I have located their location along the x-axis (from a stem plot of the coefficients of the signal, which I acquired via fft). If anyone knows how such a thing is done I would appreciate it.
Take Care, Matt

If you have the Signal Processing Toolbox, use the findpeaks function. If you don’t there’s at least one ‘peakfinder’ function in the File Exchange.
