• Understanding of AC and DC behavior of passive devices (resistor, capacitor, inductor)
• Basic understanding of diodes and BJTs

Engineering Science: 100%

ECE206 is the lab course which builds on ECE 205 concepts; ECE 205 is an introductory course in circuit analysis for non-majors in engineering. The goals are to supplement the material of ECE 205 and provide a hands-on experience in assembling and testing electric and electronic circuits.
