Hello,

  I am looking for the relationship between amplitude in the freq domain and time domain. 

For example consider a sine wave with freq 2Hz and amplitude 20 in the time domain. When I FFT it, I get an impuse in the Freq at 2 Hz with a peak different from 20. How are these two related and how can I get them to be equal ?

Thanks for all the help.
