Hi, I have question about the following attachment.
I have to sketch ACF of the output response.
I know that I have to cross multiply and sum the terms to get the output sequence. I have followed through examples and I cant get it working and I am not sure where am I going wrong. Can someone shed some light please?
I have worked out j(m) as 1,-4,6,-4,1
i now need to work out output sequence and not sure how
