To see this, put Ai: Chapter 5 Problem Solutions 87 Next, define the scalar Y: Chapter 4 Problem Solutions 51 Since Y is also Gaussian, the components of Y are independent. Click here to sign up. We also note from the text that the sum of two independent Poisson random variables is a Poisson random variable whose parameter is the sum of the individual parameters.

Beyond that, the Chernoff bound is the smallest. Conversely, if the quantity in square brackets is equal to fn x1. See previous problem solution for graph.

Our proof gubnerr by contradiction: Although the problem does not say so, let us assume that the Xi are independent. Hence, Wt is a Markov process. Chapter 9 Problem Solutions 8.

So the bound is a little more than twice the value of the probability. Hence Xt is first-order strictly stationary. For arbitrary events Gnput Fn: It will then follow that the increments are independent.

Let Xi be the price of stock i, which is a geometric0 p random variable. Since the mean is zero, the second moment is also the variance. Hence, Xt is not WSS. Then if we put u t: Help Center Find new research papers in: Hence, Yn is WSS. Hence, S0 f is real and even. Since the Xi are independent, they are uncorrelated, and so the variance of the sum is the sum of the variances. Similar to the solution of Problem Hence, the collection is closed under complementation. It is similar to show that the distribution limit of Xt is also N 0, 1.

Assume the Xi are independent. But this implies Xn converges in distribution to X. We next compute the correlations.

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

Therefore, the answer is b. We must check the four axioms of a probability measure. By Problem 11, V 2 is chi-squared with one degree of freedom. Let hn Y be bounded and converge to h Y.

We must show that B is countable. The solution is very similar the that of the preceding problem.

## Frame ALERT!

The mean of such a pmf is j p. The event that the friend takes two chips is then T: Now, any set in A must gubnre to some An. If all An are countable, then n An is also countable by an earlier problem.

T c First note that by part aA: Let A denote the collection of all subsets A such that either A is countable or A c is countable. In other words, as a function of i, pX Z i j is a binomial j, p pmf. Let W denote the event that the decoder outputs the wrong message. If we can show that each of these double sums is nonnegative, then the limit will also be sollutions.

Thus, X and Y are jointly Gaussian. 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: The plan is to show that solutionz increments are Gaussian and uncorrelated. We now need the following implications: If we put Z: Hence, its integral with respect to z is one.
