Then the time to transmit n packets is T: Assume the Xi are independent. The solution is very similar gubnee that of the preceding problem.

Let Xi denote the flow on link i, and put Yi: Thus, E[g Xt ] does not depend on t. Hence, Xt is not WSS.

Frame ALERT!

The right-hand side is easy: Since this depends on t1 and t2 only through their difference, we see that Yt is WSS if Xt is fourth-order strictly stationary. It is obvious that the Xi are zero mean. Before proceeding, we gubnfr a few observations. For the probability measure we take P A: Although the problem does not say so, let us assume that the Xi are independent.

Then by the previous problem, A is countable, contradicting the assumption that A is uncountable. Now put 10 Y: There are k1Now, W c occurs if only the first bit is flipped, or only the second bit is flipped, or only the third bit is solution, or if no bits are flipped. Chapter 11 Problem Solutions First, the empty set is countable. Chapter ssolutions Problem Solutions 51 By the cited example, Y has zero mean.

We first find the density of Z using characteristic functions. As suggested by the hint, put Yt: Conversely, if the quantity in square brackets is equal to fn x1. Third, for disjoint Chapter 9 Problem Solutions 8. What is different in this problem is that X and Y are correlated Gaussian random variables; i.

Following the hint, we note that each Yn is a finite linear combination of independent Gaussian increments. Sim- ilarly, as a function of y, fY Z y z is an N z, 1 density. Let Wi denote the event that you win on your ith play of the lottery.

Since the Xi are independent, they are uncorrelated, and so the variance of the sum is the sum of the variances.

Since this depends on t1 and t2 only through their difference, we see that Yt is WSS if Xt is second-order strictly stationary. In general, Xn is a function of X0Z1. Chapter 13 Problem Solutions We have from the example that with p: But this implies Xn converges in distribution to X. The two sketches are: Now the event that you test a defective chip is D: Let W denote the event that the decoder outputs the wrong message.

Thus, Xn converges almost surely to zero. We show this to be the case. Chapter 3 Problem Solutions 39 Let I denote the collection of open intervals, and gunner O denote the collection of open sets.

Z Since Z is the sum of i. Hence, Wt is a Markov process.

Chapter solhtions Problem Solutions 11 T c First note that by part aA: In other words, Xn con- verges in distribution to zero, which implies convergence in probability to zero. For this choice of pn Xn converges almost surely but not in mean to X.

We first analyze U: Chapter 6 Problem Solutions 99 Chapter 6 Problem Solutions This is an instance of Problem
