I'm trying to resolve this exercise but I don't even know where to start. Do I have to apply convolution?
**It appears that this question is classified as homework - this an exame problem which I was/am studying **, not homework per se
The "simple" doubt was I had no idea where to start -The answer by Fat32 helped me a lot: "express the input x1[n] in terms of shifted and scaled copies of x0[n]"
I can upload the resolution with the graphics if this help the question.
Thank you, Eddy
