Let hn Y be bounded and converge to h Y. Sim- ilarly, as a function of y, fY Z y z is an N z, 1 density. Without loss of generality, let 1 and 2 correspond to the two defective chips. Now, any set in A must belong to some An. In particular, this means R that the left-hand side integrates to one. In the diagram, M is the disk and N is the horizontal line segment. Log In Sign Up.
We make gubbner following definition and apply the hints: We first find the density of Z using characteristic functions. Hence, X and Y are independent. Remember me on this computer. Chapter 11 Problem Solutions The plan is to show that the increments are Gaussian and uncorrelated.
The remaining sum is obviously nonnegative. Chapter 9 Problem Solutions a We assume zero means to simplify the notation. Since SX f is equal to its complex conjugate, SX f is real. We need to find the density of T. So the bound is a little more than twice the value of the probability. It remains to find the mean and covariance of Y.
Hence, we know from the text that Xt and Yt are jointly wide-sense stationary.
There are 52 gubber possible hands. The sum over j of the right-hand side reduces to h xi. Chapter 6 Problem Solutions This is an instance of Problem Since the joint characteristic function is the product of the marginal characteristic functions, X and Y are independent. All five cards are of the same suit if and only if they are all spades or all hearts or all diamonds or all clubs. Assume the Xi are independent. The 10 possibilities for i and j are 12 13 14 15 23 24 25 34 35 45 For each pair in the above table, there are three possible values of k: There are two cases.
Since this depends on t1 and t2 only through their difference, we see that Yt is WSS if Xt is second-order strictly stationary. We claim that the required projection is 01 f t dWt.
Thus, E[g Xt ] does not depend on t. Since this depends on t1 and t2 only through their difference, we see that Yt is WSS if Xt is fourth-order strictly stationary. Since the Wiener process is Gaussian with zero mean, so is the process Zt. We now show that this last factor is equal to gubmer.

Let Xk denote the number of coins in the pocket of the kth student. Chapter 4 Problem Solutions 53 As pointed out in the discussion at the end of the section, by combining Theo- rem 8 and Theorem 6, the chain has a unique stationary distribution.
What is different in this problem is that X and Y are correlated Gaussian random variables; i. We next compute the correlations. Consider the i j component of E[XB].
Chapter 3 Problem Solutions 39 Thus, Xt is WSS. Let Nt denote the number of crates sold through time t in days. Suppose A is countable and B is uncountable. Then Xn converges in probability to X and to Y.
We now use the fact that since each of the terms in the last line is a scalar, it is equal to its transpose.
Third, for disjoint For XbN is to be the projection of XbM onto Guber, it is sufficient that the orthogonality principle be satisfied. As it turns out, we do not need the interarrival times of Mt. In order that the first header packet to be received is the 10th packet to arrive, the first 9 packets solytions be received must come from the 96 data packets, the 10th packet must come from the 4 header packets, and the remaining 90 packets can be in any order.
