Let x and z be zero-mean, jointly gaussian random variables with variances v2 and v2 , respectively, and correlation coefficient t. (a) express z as a linear combination of x and gaussian r. v. y that is independent of x. find the linear combination and the variance v2y of y in order that z has variance v2z , and x and z have correlation coefficient t. (b) use the result of (a) to you prove that e[x2 z2] = e[x2]e[z2] + 2e[xz]2 . (hint: you may find it to review the solution to problem 6b of problem set 9x.) (c) let x(t) be a zero-mean, wide-sense stationary gaussian random process with autocorrelation function rx (x). the output of a "square-law detector" is y(t) = x(t)2 . use the result of (b) to show that ry (x) = rx (0)2 + 2r2x (x).

10 points? ? +++ me asap gabriella uses the current exchange rate to write the function, h(x), where x is the number of u. s. dollars and h(x) is the number of euros, the european union currency. she checks the rate and finds that h(100) = 7.5. which statement best describes what h(100) = 75 signifies? a) gabriella averages 7.5 u. s. dollars for every 100 euros. b) gabriella averages 100 u. s. dollars for every 25 euros. c) gabriella can exchange 75 u. s. dollars for 100 euros. d) gabriella can exchange 100 u. s. dollars for 75 euros.
