Now, since each of the above terms on the third line is a scalar, each term is equal to its transpose.

### Errata for Probability and Random Processes for Electrical and Computer Engineers

The solution is very similar the that of the preceding problem. As discussed in the text, for uncorrelated random variables, the variance of the sum is the sum of the variances. Hence, its integral with respect to z is one.

It suffices to show that Yn is Cauchy in L p. Help Center Find new research papers in: Although the problem does not say so, let us assume that the Xi are independent. But f x must be one of the values y1. We claim that the required projection is 01 f t dWt. See previous problem solution for graph. For arbitrary events Fnlet An be as in the preceding problem.

Since this depends on t1 and t2 only through their difference, we see that Yt is WSS if Xt is fourth-order strictly stationary. Let Ti denote the time to transmit packet i. More specifically, there are 96 possibilities for the first packet, 95 for the second. We must show that B is countable. For example, if the friend takes chips 1 and 2, then from the second table, k has to be 3 or 4 or 5; i. Let Nt denote the number of crates sold through time t in days.

Poisson 1then Tn: There are k1By the hint, the limit of the double sums is the desired double integral. solutiins

We next compute the correlations. Since we do not know the distribution of the Xiwe cannot gubher the distribution of Tn. Since Xn converges in mean square to X, Xn converges in distribution to X. Here i and j are the chips taken by the friend, and k is the chip that you test.

Then the Xk are independent and is uniformly distributed from 0 to 20; i. We must first find fY X y x. Then differentiate to obtain the density. We know from our earlier work that the Wiener integralR is linear on piecewise-con- R stant functions. For this choice of pnXn converges almost surely and in mean to X.

Similar to the solution of Problem Then E does not belong to A since neither E nor E c the odd integers is a finite set. We zolutions point out that this is not a question about mean-square convergence. Assume the Xi are independent. Since the Xi are independent, they are uncorrelated, and so the variance of the sum is the sum of the variances.

Let hn Y be bounded and converge to h Y. Third, let A1S, A2.

In other words, Xn con- verges in distribution to zero, which implies convergence in probability to zero. We show that the probability of the complementary event is zero. Thus, pn is unbiased and strongly consistent. Let W denote the event that the decoder outputs the wrong message. To see this, put Ai: The 10 possibilities for i and j are 12 13 14 soluitons 23 24 25 34 35 45 For each pair in the above table, there are three possible values of k: The plan is to show solutkons the increments are Gaussian and uncorrelated. Now the event that you test a defective chip is D: In the first case, since the prizes are different, order is important.
