Problem7) Suppose that N(t) is a zero-mean stationary narrowband process. The autocorrelation function of the equivalent lowpass process Z(t) = X(t)+ jY(t) is defined as Rz(t) = E [Z*(f)Z(t +t)] a. Show that E[Z(t)Z(t+t)] = 0 b. Suppose R,(t) = No8(t), and let V = Z(t)dt Determine E [V2] and E [IV?].

Problem7) Suppose that N(t) is a zero-mean stationary narrowband process. The autocorrelation function of the equivalent lowpass process Z(t) = X(t)+ jY(t) is defined as Rz(t) = E [Z*(1)Z(t + t)] a. Show that E[Z(t)Z(t + t)] = 0 b. Suppose R:(r) = No8(t), and let V = Z(t) dt Determine E [V2] and E [IV]2].
