Homework 5

Date Assigned: Thursday, February 20, 2003
Date Due: Tuesday, March 4, 2003

  1. Exam 1 will be on Tuesday, February 25, 2003. The topics for the exam will include Chapter 1 of the text and the digital communication application.

  2. Reading: Please study Chapter 2, Sections 2.1-2.4.

  3. Please solve the following problems in the text:
    Chapter 2: 2.2.3, 2.2.4, 2.2.5 (draw a tree), 2.2.6, and 2.2.9 (in part d, n refers to the number of tries before generating a busy signal).

  4. Presentations: You may recall from the course syllabus that each student will have the opportunity to deliver a presentation to the class. We will begin the presentations on March 4. I would like the following students to present their solution to Problem 2.2.9:
    Ig An and Rich Carter
    The students will present their solution as a group, so they should get together before class on March 4.

  5. Develop a MATLAB simulation program for the salesperson model discussed in class. That is, you should simulate a large number of trials, and determine the probability of at least one successful sale in N sales calls, assuming that the calls are independent and that p is the probability of a successful sale on a call. Perform a simulation for the case of N = 10 calls and p = 0.2. Compare your simulation result with the analytical result, and please submit a printout of your MATLAB program.

    Please answer the following questions using analysis, not simulation.

    Explain your reasoning.

  6. Please see Homework 6, which will be due on Thursday, March 6. You may want to begin the problems on Homework 6 before March 4.
Thank you.
