EE 465 : Homework 7 Due : 11/4/2008, Tuesday in class. 1. Solve 6.6 (6.6) (do parts (a) and (b) only) from textbook 2. Solve 6.12 (6.12) from textbook 3. Solve 6.13 (6.13) from textbook 4. Solve 6.15 (6.15) from textbook 5. Solve 6.17 (6.17) from textbook 6. Solve 6.22 (6.22) from textbook 7. Consider a simple telephone switching center where calls arrive according to a Poisson process of rate λ . The center has two switches: A and B. Each arriving call is routed to switch A with probability p and to switch B with probability 1 - p . Switch A has capacity C A (can handle C A calls simultaneously) and switch B has capacity C B . When a routed call finds the switch full, it is simply blocked and rejected. Call durations are exponentially distributed with rate μ . (i) Compute the blocking probability of switch A. (ii) Compute the blocking probability of the center. (iii) Suppose there is only one switch in the center with capacity C A + C B . Compute the blocking probability of the center.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
