WebbIt is often useful to characterize a random variable by its mean and vari-ance. Therefore the following quantities are of primary interest. E[x] is the expected value of x: E[x2] is the average power of x: E[(x E(x))2] is the variance of x: Note that the mathematical expectation operator E[x] is a linear operator.
