ECE 3800 Exam#2 Spring 18 ECE 3800, Probabilistic Methods of Signal and System Analysis Page 5 of 6 4 30 pts) An ECE student on main campus attempts to catch the 9am bus every morning although his arrival time at the bus stop is a random variable that is exponential distributed beginning at 850 am as described below. PROBLEM54Suppose a BPSK receiver observes r = a n, where a ∈{±1} with a priori probabilities Pa(1) = p and Pa(–1) = 1 – p, and where the noise is independent of a with a Gaussian distribution n –∼ N( ,1), so that so that its pdf is fn(x) = e (x – ) 2/2 (Remark Noise is usually zero mean, so the fact that the mean of the noise might be nonzero.

4 8 Let X be a discrete random variable taking on the two values ±10 with equal probability Let Y be a uniform random variable on the interval (1,1) If Z = X Y, and X and Y are independent, find the probability density function for the random variable Z 9a First see if the joint density factors into two parts, one of which depends only on x and the other of which depends only on y. @X^ E(X X^)2 Y = 2 Z 1 1 (x X^)f XjY(xjy)dx @ @X^ E(X X^)2 Y = 0 ) 2 Z 1 1 (x X^)f XjY(xjy)dx= 0 Therefore, X^ Z 1 1 f XjY(xjy)dx= Z 1 1 xf XjY(xjy)dx ) X^ MMSE= EXjY Corollary 1 The conditional MSE corresponding to X^ MMSE is E(X X^ MMSE)2jY = ˙2 XjY Proof The proof directly follows from the de nition of the variance E(X X^. 2/22/13 ECE 595, Prof Bermel • The discretization of the continuity equation in conservative form requires the knowledge of the current densities on the midpoints of the mesh lines connecting neighboring grid nodes Since solutions are available only on the grid nodes, interpolation schemes are needed to determine the solutions.

Nov 29, 16 · Yes, EEX = EX This is because EX is just a number, it's not random in any way So when we ask for EEX, ie, our best guess for the number EX, well since EX is just a constant number which is not random, we know its value, so.

In probability theory, the expected value of a random variable, denoted ⁡ or ⁡ , is a generalization of the weighted average, and is intuitively the arithmetic mean of a large number of independent realizations of The expected value is also known as the expectation, mathematical expectation, mean, average, or first momentExpected value is a key concept in economics, finance, and many.
