► Problem 1.9 Categorize each of the following signals as an energy signal or a power signal, and find the energy or time-averaged power of the signal: t, 0 ≤t≤ 1 (a) x(t) = - 2 t, 1sts 2 0, n, otherwise 0≤n<5 (b) x[n] = - 10 n, 5≤ n ≤ 10 otherwise (c) x(t) = 0, 5 cos(t) + sin(5πt), -∞ <t< ∞ 5 cos(t), 1st≤1 (d) x(t) = 0, otherwise 5 cos(t), -0.5 ≤ ≤ 0.5 (e) x(t) = 0, otherwise (f) x[n] = sin(n), -4 n≤4 0, otherwise cos(πn), -4≤ n ≤4 (g) x[n] = 0, otherwise (h) x[n] = { cos(n), n≥0 0, otherwise
