Course Goals

ECE 205 is an introductory course in circuit analysis for nonmajors in engineering. The goals are to impart the fundamental principles of electric circuits, semiconductor devices, and electronic circuits that constitute the foundation for preparing a nonmajor to take followon courses involving electric and electronic circuits. The lab work is provided in ECE 206.
