Hi
I have a signal that I perform FFT on. When I perform IFFT on the FFTed signal I dont get back the old signal. Where am I wrong?
My signal is waveform2. I used FFT and IFFT as:
fftvalue= abs(fft(waveform2));
ifftvalue=real(ifft(fftvalue));
Ifftvalue and waveform2 are not same. Is it supposed to be like that or Am i missing something here? Please help. Thanks.
