LATE HW POLICY: Effective 10-12-07, each student will be allowed to turn in one homework up to one week late. All other late homeworks or homeworks over one week late will receive zero credit.

Course Overview

• Class meets MWF at 11AM in Duncan Hall 1064.
• Laboratories will be held Wednesday and Friday afternoons from 2-5 PM and Thursdays from 2:30-5:30PM, all in Abercrombie A141.
• Concept review session Mondays, 7-9PM, DH 1042

The course focuses on the creation, manipulation, transmission, and reception of information by electronic means. Elementary signal theory; time- and frequency-domain analysis; Sampling Theorem. Digital information theory; digital transmission of analog signals; error-correcting codes. Laboratory demonstrating the principles of information management by electronic means.
Prerequisites: Math 101, 102.
