SUMMARY

The discussion centers on the application of Fourier Transformation (FT) in converting time functions into frequency functions. It highlights that FT is primarily utilized to analyze how systems respond to different frequencies within a complex forcing function. By examining individual frequency responses, one can gain insights into the system's behavior, making FT a valuable tool in signal analysis.

I am sorry 2 ask this...
I still don't 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 separate frequency. That's why it's usefull to have a signal analysed on the separate frequencies.
