Hi,

How time domain signal is represnt in freq domain?
that means How how forrier transform map the time domain signal into Freq domain. so we get freq information of signal.

Regards,
Naresh
 

Forrier Transform

First of all, its "Fourier" and not Forrier.. What fourier transform does is to compare the given signal with each of the frequency domain frequencies and the correlation gives the amout of each freq content. It is easier said than done. If you go through the bascis of signals and systems, you will understand..
 

Re: Forrier Transform

if u can use matlab for doing the fourier and plot the graph u can easily understand the difference between those. fourier transform converts time domain to frequency domain and the frequencies that are existing in the signal are existing are obtained.
 

Re: Forrier Transform

any signal(e.g speech) can be synthesized using summation of sinosoids. fourier transform(used for continous and non-periodic data) gives the contribution of all sinosoids (each with different frequency) in the synthesis of a particular signal.
