Description: ES 332 (Electrical Engineering) provides fundamental topics of electrical engineering to non-majors. Topics include circuits (DC and AC analysis, operational amplifiers and power) and digital systems (binary numbers, logic and information processing). The course will cover material taken from chapters 1-5, 11-15 of the text.
