I have been doing DTFT practice problems for my DSP course, and I encountered this problem in the textbook that completely stumped me.
The question asks to find the DTFT of the shown signal and to plot its magnitude and phase. I am very comfortable with doing this with real-valued signals, but have no idea where to start when it comes to complex signals. Especially how the plotting would be done. I would appreciate any advice on how to tackle the problem.
