MOHAWK VALLEY COMMUNITY COLLEGE UTICA AND ROME, NEW YORK CENTER FOR SCIENCE, TECHNOLOGY, ENGINEERING AND MATHEMATICS COURSE OUTLINE I. CATALOG DESCRIPTION: ET161 Linear Electronics C-2, P-2, CR-3 The theory and applications of modern transistors are introduced; both the bipolar junction transistor and the field effect transistor are examined. Applications include usage in small and large signal class A amplifiers, as well as in class B power amplifiers. Voltage control FET applications are studied. Problem solving techniques involving digital computers are discussed. II. III. Prerequisites: ET153 Introduction to Electronics, ET154 Computer Programming, or permission of instructor. Corequisites: ET152 Circuits 2 or permission of instructor. MATERIALS: Text: Electronic Principles, 7th edition, ISBN #0073222776, by Malvino, McGraw-Hill Publishing Lab Manual: Laboratory Manual for Linear Electronics, by Fiore. Available on-line at www.mvcc.edu/jfiore and at open educational resource sites Tools: Scientific calculator, electronic hand tools and breadboard STUDENT LEARNING OUTCOMES: The student will demonstrate familiarity with the operating principles and linear applications of bipolar and field effect transistors. (a) The student will demonstrate a working knowledge of the basic theory of device operation, how to properly bias devices, and have an understanding of common circuit applications including small and large signal audio amplifiers. (a) The student will use a mathematical and problem solving approach for design and analysis, based on fundamental DC and AC circuit principles and math concepts. This will include the use of computer simulations. The student will demonstrate facility at constructing and trouble shooting transistor circuits in the laboratory with proper use of test equipment.
