Determine whether the following systems are BIBO (stable), memoryless, and causal:
a) h(n) = 2u(n) - 2u(n-1)
b) h(t) = e^(-|t|)
c) h(t) = e^(2t)u(t - 1)
Find the output of the following continuous-time systems:
a) x(t) = rect(t/4) and h(t) = sin(2Ćā¬t) for 0 < t < 1/4
b) y(t) = p(t)u(t - 1) and n(t) = x(q)
