Consider a LSI system whose impulse response is h[n] = (1-116[n-k]. Assume that all the initial values are zeros in the system. Under the D B k=-9 assumption, the LCCDE of the system is: duln-k] =pa[n-k]. k = A Find the value(s) or the expression(s) of d, and p, in the LCCDE. (10 pts) Find the values of A. B. C. and D in the LCCDE. (5 pts) Is the system causal? If No, what is the smallest time-shift value necessary to make the system causal? (5pts)
