hi,
Taking ifft of a frequency domain signal gives you a composite signal having all the frequencies which you specify in the frequency domain. Like if you make your signal in frequency domain as {0+i, 0,1,0,0,1,0, 0-i}, you will get a signal having two frequencies corresponding to the elements 0+i and 1. When you take the FFT of this signal, it will dwecompose the signal into its frequency domain constituents i.e. your frequency domain elements.
I mean..
Example : N = 8
decomposing N at time domain
0 1 2 3 4 5 6 7
0 2 4 6 1 3 5 7
0 4 2 6 1 5 3 7
is true? (reverse bit!). Log2 N step = 3 step, we compute the process using butterfly...
now we enter to domain frequency, Is true?
How to decomposing sinyal on domain frequency, is like at time domain? or...
