The changes for ES 3 Introduction to Electrical Engineering are described below.
1. The change in the bulletin description is presented in italicized type font below:
ES 3 Introduction to Electrical Engineering
Definitions of circuit elements, fundamental laws, selected network theorems, controlled
sources, introduction to the oscilloscope, energy and power, natural response and
complete response of first order circuits, steady state sinusoidal behavior, algebra of
complex numbers, phasors, impedance, average and reactive power, introduction to
analog and digital systems, frequency response and filters, measurements and
instrumentation, introduction to computer applications for circuit analysis and design.
Associated laboratory project work. Prerequisite: must be preceded or accompanied by
Math 12.
2. The rationale for making the changes to the course was to widen the scope to reflect to
a broader based introduction to the field of electrical engineering and transition it away
from an introduction to electrical circuit course as it has been taught in the past. This
change is to meet the needs of other departments in the School of Engineering to cover
topics which included measurement, computer instrumentation, analog and digital
systems, and a more meaningful laboratory. The laboratory will be presented with a
thematic set of experiments which provide the students with hands-on experience and
feedback as they build, measure, and make design improvements to an analog and digital
audio system
3. The modifications to the course require selection of a new textbook, additionally
course notes by the instructors, and a modifying the set of laboratories to reflect the
thematic approach of designing and testing an audio system. Professors Jeff Hopwood,
Denis Fermental, Vo Van Toi, and Ron Lasser are writing the set of 5 laboratories:
a. Lab 1: DC measurements – Measure resistance of commercial speakers,
headphones, etc. Determine length of wire and wire gauge needed for an
8 ohm speaker
b. Lab2: AC measurements – Measure inductor and capacitor impedance.
Correlate frequency and amplitude with the sound produced by a speaker.
Measure speaker inductance and (acoustic) loss ( jL+ R)
c. Lab 3: Thevenin Equivalent Circuits and Loading – Understand how a
load on a device will reduce the output voltage signal if the impedance
(Zload) is much less than the Thevenin resistance (RTh) and equal to the
output resistance (Rout). Introduction of block diagram of a generic

amplifier and the terms input resistance (Rin), amplifier gain (Av), and
output resistance (Rout)
d. Lab 4: Frequency response and simple filters – Understand high frequency
limitations of the speaker (i.e., mass). Determine the upper and lower cutoff frequencies. Design a high-pass filter to improve the speaker's treble
response
e. Lab 5: D/A and A/D, MatLab and simple digital filters – Understand
digital signals vs. analog signals. Understand simple digital filtering
