Fourier Transformation

  1. Oct 29, 2004 #1
    I am sorry 2 ask this...
    I still dont understand FT.

    What is the use of converting a time function to frequency function?

    Can anybody explain it with a simple example ???

    It is just used to find the power of each frequency, other than that little other information is given in the graph of an FT so I don't know what to tell you.

    Response systems react differently on each frequency of a complex forcing function. So you can analyse a certain response by looking at the individual response of the system on each seperate frequency. That's why it's usefull to have a signal analysed on the seperate frequencies.
