hey guys - attached is a solution to a signals related question.
Given the system - we must calculate the impulse reponse.
please click on attachment to see what I am talking about.
two things confuse me:
1)the system is evidently non-causal, but here they decide to shift the entire system by two units; thus making it causal! - how can they just do this?!
2) near the conclusion of the answer they have:
h[0]=0
h[1]=1.5
h[2] =-1.5
where do they get these values??
thanks very much.
John
