Re: HELP:spectral time-frequency analysis using fourier algo
You have to just take the FFT of the signal and then take the square of the components thereafter .
By plotting this graph you can get the PSD graph of the signal.
P.S. If your doing in MATLAB then fft,square,plot...
The best thing that you can do is to download octave(www.octave.com) it is a tool which is same as matlab and is a key yo understand basic functionalities in DSP .
After this start with Richard lyons this is one of the simplest books around and then implement everything or the...
