I just realized what was happening. When I multiplied the transformed signal by the gaussian, I canceled out the negative frequency components. So of course when I transformed back the signal would be complex. I was expecting it to be a real sinusoid not a complex one.

I'm not sure if this is the right place to post this, but I'm trying to write a python script that takes a noisy multi frequency signal, transforms it to frequency space, windows it there with a gaussian, then transforms it back to time space. Here is what I wrote: Fs=1000 #sampling...
