Extracted text: 1 When measuring a direct current (DC) signal with additive white Gaussian noise, the measured signal measured in Volt is modeled as an independent and identically distributed random sequence Xn with expected value E[Xn] = 1 and standard deviation ox, = 0.5. (a) Find the auto-correlation function Rx[m, 0] = Rx[0] and auto-covariance function Cx[m, 0] = Cy[0] of the measured random sequence Xn. (b) Find the auto-correlation function Rx[m, 1] = Rx[1] and auto-covariance function Cx[m, 1] = Cx[1] of the measured random sequence Xn.
