PSpice and Orcad Capture are computer programs that simulate electric circuits. PSpice for Linear Circuits provides an introduction to these programs and describes ways in which they can be profitably used in an introductory course on electric circuits. This manual is written specifically for beginning electric circuits students, and gives step-by-step instructions for using PSpice and Orcad Capture to analyze ac and dc circuits, circuits in the time domain to determine the complete response, and circuits in the frequency domain to determine the frequency response.
