Description: Thistext is written for use in a second course in circuit analysis. The reader of this book should have
the traditional undergraduate knowledge of an introductory circuit analysis material such as Circuit
Analysis I with MATLAB® Applications by this author. Another prerequisite would be knowledge of
differential equations, and in most cases, engineering students at this level have taken all required
mathematics courses. It encompasses a spectrum of subjects ranging from the most abstract to the
most practical, and the material can be covered in one semester or two quarters. Appendix B serves as
a review of differential equations with emphasis on engineering related topics and it is recommended
for readers who may need a review of this subject. -Thistext is written for use in a second course in circuit analysis. The reader of this book should have
