Let X and Y are statistically independent Gaussian-distributed

Let X and Y are statistically independent Gaussian-distributed Let X and Y are statistically independent Gaussian-distributed random variables, each with zero mean and unit variance. Define the Gaussian process Z (t) = Z cos (2pt) + Y sin (2pt) (a) Determine the joint probability density function of the random variables Z (t1) and Z (i2) […]

Let X (t) is zero-mean, stationary, Guassian process with

Let X (t) is zero-mean, stationary, Guassian process with Let X (t) is zero-mean, stationary, Guassian process with autocorrelation function RX (t). This process is applied to a square-law device, which is obtained by the input-output relation Y (t) = X2 (t), where Y (t) is the output (a) Show that the mean of y […]

Let R denote the random variable obtained by observing the Let R denote the random variable obtained by observing the output of an envelope detector at some fixed time. Intuitively, the envelope detector is expected to be operating well into the threshold region if the probability that the random variable R exceeds the carrier amplitude […]
