This course builds on the introductory course ELE202 in electric circuit analysis. The course topics include a brief overview of circuit variables, elements, laws and theorems; mutual inductance and the ideal transformer model; 3-phase circuits; the operational amplifier as an active circuit element. Also, simple opamp circuits, the Laplace transform with applications to differential equations and electric circuits, frequency responses, Bode plots, resonant circuits, Fourier series; two port networks, and network parameters for interconnection of two-port networks; use of PSpice simulation software to solve circuit problems.
