Two LTIC systems have impulse response functions given by h1(t)=(1-t)[u)t)-u(t-1)] and h2(t)=t[u(t+2)-u(t-2)].
a) Carefully sketch the functions h1(t) and h2(t).
b) Assume that the two systems are connected in parallel. Carefully plot the equivalent impulse response function hp(t).
c) Assume that the two systems are connected in cascade. Carefully plot the equivalent impulse response function, hs(t).
