I have a signal magnitude and phase in frequency domain. I need to have it in time domain but I really have no idea how to do it. I heard something about mirroring the signal but I'm kinda new at this. I have tried to do something like this in matlab but I'm clearly missing the point. And how do I define the time vector?
z = A .* exp(i*phase); X = ifft(z);
I've attached the signal plot https://i.stack.imgur.com/FfbTV.jpg
