I got some data which is in equal time stamps. When I do the Fast Fourier Transform for the data using matlab I get the graph below. Now I understand how to do the fast fourier transform but I have no idea what information the FFT graph gives.(adsbygoogle = window.adsbygoogle || []).push({});

I am confused as to what the peak at 1 represents and what else I can gather from the FFT?
