Description: This is the second undergraduate course in electric circuits. It focuses on AC circuit analysis, the analysis of a passive circuit's response to time-varying sources, and introduces frequency response concepts used in passive and active filter design. AC circuit analysis is an essential tool for those working with electric power grids. It uses complex-valued phasors to characterize the sinusoidal signals found in power systems. To properly design and interface embedded devices to the outside world, it is essential that the engineer be able to predict how a given circuit might respond to time-varying inputs. The main tool one uses to predict a circuit's dynamic response is the Laplace transform; a mathematical operator that transforms time-domain circuit models (i.e. differential equations) into complex valued algebraic models (i.e. transfer functions). This approach allows one to characterize a circuit's response in terms of its frequency response and provides a widely used conceptual basis for circuit analysis and synthesis.
