The intent is to use experiments as a vehicle for gaining a sound foundation for further study of electrical engineering. Course Designation: Required for EE and CE Text Book: J.P. Parekh, Analog Electrical Circuits for the Beginner, 2004 Plus class notes on digital circuits Prerequisites: Corequisite: Coordinator: Jayant P. Parekh Goals: 1) To provide experience with wired experiments and measurements in the lab 2) To provide the student with an ability to predict the performance of a wired circuit through computer simulation of experiments 3) To provide concepts and theory relevant to experiments, including varying degrees of ability to analyze or design circuits, through lectures Objectives: Upon completion of this course, students will have learnt: 1) how to perform simple DC and AC analog circuit experiments involving resistors, capacitors, diodes, and BJTs; and logic circuit experiments involving gates, flip-flops, counters, etc. 2) how to analyze and design simple analog circuits (DC and AC); and simple logic circuits (combinational and sequential); 3) computer simulation techniques using Electronics Workbench 4) Microsoft Excel as an analog circuit problem solving and graphing toolTopics Covered: Week 1.
