Consider an LTI system with the input and output related by y[n]=0.5(x[n+1]+x[n]) Chap. 10 Problems 547 (a) Find the system impulse response h[n]. (b) Is this system causal? Why? (c) Determine the system response y[n] for the input shown in Figure P10.17(a). (d) Consider the interconnections of the LTI systems given in Figure P10.17(b), where h[n] is the function found in Part (a). Find the impulse response of the total system. (e) Solve for the response of the system of Part (d) for the input of Part (c).
