Consider the sum of two ergodic noise voltages:
The power of n1(t) is 5 W, the power of n2(t) is 10 W, the DC value of n1(t) is -2 V, and the DC value n2 is +1 V. Find the power of n(t) if
(a) n1(t) and n2(t) are orthogonal.
(b) n1(t) and n2(t) are uncorrelated.
(c) The cross-correlation of n1(t) and n2(t) is 2 for t = 0.
