University of Illinois at Urbana-Champaign Department of Electrical and Computer Engineering ECE 459: Communications I Fall 2004 Problem Set 10 Pulse Amplitude Modulation, Pulse Code Modulation Issued: Thursday, December 2nd. Due: Never. Reading from Lathi: Sampling and Pulse Amplitude Modulation: Chapter 6, Section 6.1 and Chapter 7, Section 7.3; Quantization and Pulse Code Modulation: Chapter 6, Section 6.2. Reading from Haykin (3rd Edition): Sampling and Pulse Amplitude Modulation: Chapter 6, Sections 6.1–6.4; Quantization and Pulse Code Modulation: Chapter 6, Sections 6.7–6.10. Announcement: The Final Exam will be held on Monday, December 13th, from 1:30pm to 4:30pm in 165 Everitt Laboratory. The exam will cover all material from the beginning of the term. For the exam, you can bring three 8.5×11-inch double-sided sheets of handwritten notes. Calculators are allowed but will not be necessary. A copy of an old final exam will be available from http://courses.ece.uiuc.edu/ece459/fall04/ . This sample exam does not necessarily resemble this year’s exam (also notice that the material covered in this old final exam is slightly different from the material covered in this year’s final exam). Problem 10.1 Problem 6.1-2 from Lathi, p. 289. Problem 10.2 Problem 6.1-5 from Lathi, p. 290. Problem 10.3 Consider the pulse amplitude modulation (PAM) scheme shown below. - - - mδ(t) s(t) SAMPLER FILTER SHAPING PULSEm(t) The output of the sampler is given by mδ(t) = +∞∑ k=−∞ m(kT )δ(t − kT )
