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.
