(a) Consider the two LTI systems cascaded in Figure P10.11. The impulse responses of the two systems are identical, with h₁[n] = h₂[n] = (0.6)ⁿu[n]. Find the impulse response of the total system.

(b) Repeat part (a) for h₁[n] = h₂[n] =

(c) Write out the terms in part (b), as in (10.15), to verify the results.

(d) Repeat part (a) for h₁[n] = h₂[n] = u[n] - u[n - 3]. Express the results ii terms of impulse functions.
