A Few Notes on Complex Numbers
Purpose: The complex number system provides a means of mathematically expressing the the even roots of negative numbers. For example, while there is no problem
with taking the cube-root of (-8) since 3 8 = 2, what is to be d

Introduction to Laplace Transform
Techniques in Circuit Analysis
In this unit we consider the application of Laplace Transforms to circuit analysis. A
relevant discussion of the one-sided Laplace transform is found in Chapter 12 of the
text.

Inductance and Capacitance
Inductors and capacitors are devices which store energy:
Inductors store energy in magnetic elds eg., elds within a coil. According
to Faradays law, a time-varying magnetic eld arising from time varying currents
within t
Unit 3
Response of First-Order Systems
In this unit, we consider inductors or capacitors (but not both together) as elements
in circuits containing resistors. That is, we wish to examine resistor-inductor (RL)
circuits and resistor-capacitor (RC) circuits

Sinusoidal Steady-State Analysis
To this point in the course, the current and voltage sources appearing in the circuits we
have studied have been direct current (dc) sources. In this unit, we consider circuits
in which the sources are sinusoidal in

Response of Second-Order Systems
In this unit, we consider the natural and step responses of simple series and parallel
circuits containing resistors (R), inductors (L), and capacitors (C). The equations
which result from this analysis will, in gen
