yln]
k(n]
1.
i) Express the overall impulse response h[n] in terms of h, [n], h2[n], h3[n] and
h4[n].
ii) Determine h[n] when h, [n] = [0.5 0.25 0, 5], h2[n] = hz[n] = (n+ 1)u[n]
and h4[n] = 8[n - 2]
Determine the response of the system in the figure to the :nput
%3D
iii)
x[n] = 8[n+ 2] + 38[n- 1]-48[n- 3]
