How to display time domain signal in Frequency domain?
Hi friends,

I am trying to display time domain signal in Frequency domain using Matlab.I took frequency of signal as 100hz and sampling frequency as 1000sampels/sec

I have tried using 'fft' function but not getting.

Anyone of you give me the solution for displaying frequency spectrum for any signal using MATLAB

Thanks in Advance,
Goud

Hi

why dont include your code, it is difficult to know what you are really doing. In any case it should be something like this
fftshift(abs(fft(x)))

where x is has the values of your signal

if you think this info is useful click on "helped me" for statistics
