For each of the following signals, determine both the normalized energy and power. Tell which are power

Question:

For each of the following signals, determine both the normalized energy and power. Tell which are power signals, which are energy signals, and which are neither.(Note: 0 and ∞ are possible answers.)

(a) x₁(t) = 6e^(-3+j4π)t u(t)

(b) x₂(t) = II[(t - 3) /2] + II(t - 3/6)

(d) x₄(t) = 2 cos(4πt)

(e) x₅(t) = |t|

(f) x₆(t) = t^-1/2u(t - 1)
