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
z
is your frequency domain vector, thenX
is your time domain vector. Done! Where's the issue? $\endgroup$ – Marcus Müller Sep 10 '20 at 19:33z
is your frequency domain. There's really nothing ambiguous about that. It's kind of hard to help you understand the things you've read "somewhere" and understand what you seek when all you tell us what you don't seek. Please explain why this isn't what you need, and what you've read. $\endgroup$ – Marcus Müller Sep 10 '20 at 20:15X
so that we can actually try to understand what you want? $\endgroup$ – Marcus Müller Sep 10 '20 at 20:33
