This course
covers advanced topics in ac analysis of electric
circuits. The dependent source is introduced. The topics of source conversions,
mesh and nodal analysis, bridge networks, superpositon,
and delta-wye conversions are extended to include
sinusoidal steady-state ac analysis. The transient response of RC networks is
analyzed. The characteristics of pulse waveforms are introduced. These topics
are combined in practical applications. The Thevenin's
and Nortons's theorems are extended to sinusoidal
steady-state ac circuits. The concept of the ideal Operational Amplifier is
introduced and simple circuits analyzed using the ideal Operational amplifier
model. Circuit responses to non-sinusoidal waveforms are analyzed through the
Fourier series.
At the end of this course you will be able to:
1.)
Analyze ac networks using mesh and nodal
analysis to find voltage and current values

Course Policies
1.
No
make-up exams. All homework due at the beginning of the period. Late homework
is graded at 50%. Late lab grades reduced by 5% per working day starting from
due date.
2.
Class
attendance is required and attendance will be taken at the beginning of every
period. Students are allowed four unexcused absences. Any further absences will
reduce the TOTAL grade by 5% per day absent.
3.
The
final grade is computed with five test scores, (the final grade will count
twice). The highest 4 test scores will then be used to determine this part
(60%) of the grade.
4.
All
exams are closed book and notes unless otherwise specified.

Tutorial on Filter Analysis
1) Methods of
Analysis with Non-ideal Components
Use the ac network
analysis techniques present in the lecture to solve practical problems. Students will model non-ideal components
using simple ideal circuit elements.
2) Computer-aided
Ac Circuit Analysis-Transmission Line Simulation
This
laboratory activity gives students an opportunity to use a computer-based
analysis package in a circuit design.
Students will build a simple pi-model of a transmission line. They will then measure and calculate the
voltages that appear.
3)
Application of Ac
Bridges-Inductance Measurements
Students will
construct a Maxwell ac bridge and use it to measure inductance values. They will then compare the results to the
measurements of a commercial bridge.
4) RC Circuits: Frequency Response and Rise Time
Students observe the
transient response effects of RC circuits excited by square wave inputs. They relate the RC time constants to the
bandwidth of an RC circuit. These topics
are then used to modify the input impedance of an oscilloscope and improve its
frequency response and measurement accuracy.
5) Superposition Theorem with Ac and Dc Sources
Use the
Superposition Theorem to find the total response of ac and dc sources. Use the oscilloscope and multimeter
to measure a combined ac and dc signal.
6) Mid-term Practical Exam
This lab covers analog
Oscilloscope design and usage. The major
internal functions of an oscilloscope are present and the correct used of the
scopes controls are reviewed. A lab
practical exam covers the topics presented.

7)
Maximum Power Transfer with an Ac Source
Experimental verification of the conditions for maximum
power transfer for circuits composed of both resistive and reactive
elements. The experiment covers the
measurement of power transfer as a function of frequency. The lab is performed using circuit simulation
software.
The basic
operation of operational amplifiers is verified through experiments.

SIUC is committed to
providing a safe and healthy environment for study and work. Because some health and safety circumstances
are beyond our control, we ask that you become familiar with the SIUC Emergency
Response Plan and Building Emergency Response Team (BERT) program. Emergency response information is available
on the BERT website at www.bert.siu.edu,
Department of Public Safety’s website www.dps.siu.edu
(disaster drop down) and in the Emergency Response Guidelines pamphlet. Know how to respond to each type of
emergency.
Instructors will
provide guidance and direction to students in the classroom in the event of an
emergency affecting your location. It is important that you follow these
instructions and stay with your instructor during an evacuation or sheltering
emergency. The Building
Emergency Response Team will assist your instructor in evacuating the building
or sheltering within the facility.
