Since we do not know the distribution of the Xiwe cannot know the distribution of Tn. The plan is to show that the increments are Gaussian and uncorrelated. For XbN is to be the projection of XbM onto N, it is sufficient that the orthogonality principle be satisfied.

Let W denote the event that the decoder outputs the wrong message.

Before proceeding, we make a few observations. The second thing to consider is the correlation function. Let Nt denote the number of crates sold through time t in days. The moments of the standard normal were computed in an example in this chapter. The corresponding confidence interval is [ Chapter 4 Problem Solutions 61 We must show that B is uncountable. Then A contains each union of the form [ Ai.

Errata for Probability and Random Processes for Electrical and Computer Engineers

Chapter 11 Problem Solutions We must first find fY X y x. Now, to obtain a contradiction suppose that X and Y are independent.

Hence, Xn soluutions not converge in mean to zero. Our proof is by contradiction: Denote the arrival times of Nt by T1T2. In the first case, since the prizes are different, order is important. Chapter 13 Problem Solutions If the function q W: The table inside the back cover of the text gives the nth moment of a gamma random variable. Hence, by Prob- lem 55 c in Chapter 4 and the remark following it, 2 Z 2 is chi-squared with two degrees of freedom.

The solution is very similar the that of the preceding problem.

Frame ALERT!

Denote these disjoint events by FFFand Frespectively. First find the cdf using the law of total probability and substitution. Similarly, since the Wk are indepdendent, 2kW k2 is chi-squared with 2n degrees of freedom.

Chapter 13 Problem Solutions On the right-hand side, the first and third terms go to zero. We show this to be the case.

Here is a script: To make E[Z] For this choice of pnXn converges almost surely and in mean to X. We prove this by contradiction.

Observe that Xn takes only the values n and zero.

Let H denote the event that a student does the homework, and let E denote the event that a student passes the exam. Then E does not belong to A since neither E nor E c the odd integers is a finite set.

Here is an example.

Here we have used the Cauchy—Schwarz inequality and the fact that since Yn con- verges, it is bounded. Of course, W c is the event that the decoder outputs the correct message. It will be sufficient if Yt is WSS and if the Fourier transform of the covariance function of Yt is continuous at the origin.
