Course Objectives: The objective of this course is to extend the basic knowledge gained in EAS230 (Fundamentals and Applications of Analog Devices) to upper level network problems. This course will develop the student skills in Circuit Analysis Resistive, AC steady state, steady-state power analysis, frequency response analysis, as well as advanced techniques such as Laplace transform.

Course outcomes: At the completion of this course students should:



Be able to use the knowledge of complex numbers and algebra to develop the concepts of phasors, complex impedances, and admittances for solution of networks in the sinusoidal steady state.




Be able to apply knowledge of mathematics and engineering science to analyze electrical circuits involving sinusoidal steady state using phasors; basic problems in power systems including rms values, real and reactive power and power factor correction; resonant circuits and simple filters.




Be able to apply the knowledge of Laplace transform to develop total responses of the circuits consisting of both natural and forced responses.




Have an understanding of how Fourier Series extends steady state analysis to generalized periodic signals.




Be able to use simulation and programming packages such as PSPICE in the analysis and design of content areas including AC analysis and frequency responses.
