THE ELECTRIC CIRCUITS AND
ELECTRONICS LABORATORY
The Electric Circuits and Electronics Laboratory
OBJECTIVE
Realization of a conceptual design is probably one of the most
fulfilling experience of every engineering student. In the advent of
computer technology, the implementation of an electrical or electronic
systems design has been revolutionized through the use of various
computer simulation and hardware interface tools. Students should not
only learn the theory and concept, but in order to become competitive
and marketable, they should also know the tools and methods on how
they can implement their design using the latest technology.
The Electric Circuits and Electronics laboratory aims to fill in the
gap between conceptual theory and practical implementation of various
electrical and electronics systems covered on the lecture component of
each course.
The Electric Circuits and Electronics Laboratory is located in room
G213, it supports the following laboratory courses in the Electrical
Engineering Program,
 ELEC 201 (Electric Circuits Laboratory)
 ELEC 203 (Electric Circuits II Laboratory)
 ELEC 231 (Fundamentals of Electronics Laboratory)
 ELEC 334 (Electronics Engineering Laboratory)
MAJOR EQUIPMENT IN THE LABORATORY:
1. National Instrument ELVIS
ELVIS is an acronym which stands for Educational Laboratory Virtual
Instrumentation Suite. The unit is a highly versatile form of equipment.
Students can develop their own graphical user interface for measuring
electrical parameters such as voltage and current at various points on the actual
circuit in order to generate characteristic curves for the circuit’s response like
VTC plot, I-V plot, Bode plot during the course of their actual laboratory
work.
2. K and H ETS - 7000 Digital and Analog Training System
This trainer provides the basic needs of students during the experiment. It
includes fixed and variable dc voltage sources, function generator,
potentiometer, breadboard, pulse and data switches, speaker and digital and
LED displays
3. GW Instek Digital Storage Oscilloscopes
These instrument allows students to display and measure time base
waveforms. Alternatively, XY plots, cursor function and automatic
measurement of various electrical parameters are just some of its features.
4. BK Precision Arbitrary Waveform Generators
The laboratory is equipped with the following:

Computer Interface Adapter NI ELVIS bundled with Labview
8.2 software.

Various models of oscilloscopes, function generators and
arbitrary waveform generators.

Basic measuring devices such as portable and bench top digital
multi-meters

Analog and digital training kits with breadboard.

Multisim 8 software is installed on all computers for electrical
and electronic systems simulation.

Discrete components such as resistors, capacitors, inductors,
analog and digital integrated circuits.
These instruments can also perform the same function as function generators.
As an added feature, they allow students to generate any waveform by
reproducing a previously generated waveform or to generate waveform based
on a characteristic equation.
5. Extech- Multiview 110, True RMS Multimeter- 430,GW
Multimeter-GDM354A)
Robust and indispensible instruments for basic measurements of resistance, ac
and dc voltages and currents. They are widely used by students for developing
basic skills on electrical and electronic measurements.
CORE TEACHING TOPICS:
1. Appropriate methods for measuring various electrical parameters.
2. Verification of ohm’s law, KVL, KCL to series or parallel circuits.
3. Confirmation of mesh analysis, nodal analysis, source transformation,
superposition theorem, Thevenin’s theorem, Norton’s theorem and
maximum power transfer theorem for both ac and dc sources.
4. Verification of characteristic equations of step and source free transient
response first and second order circuits.
5. Characterization of different semiconductor devices such as diodes, BJT’s
and FET’s.
6. Verification of time response plots of half wave and full-wave rectifiers,
clipping and clamping circuits.
7. Application of operational amplifiers for linear and non-linear circuits
such as negative feedback amplifiers, instrumentation amplifiers, voltage
to current converters, phase shifters, active filters, relaxation oscillators
and waveform generators.
LICENSED SOFTWARE
1. Multisim 8.0
This software is used extensively on all laboratory activities. They allow
students to connect the circuit virtually which enables them to verify the
operation of the circuits and at the same it allows them to correct their
mistakes without causing undue harm on themselves or the equipments.
2. Labview 8.2
The accompanying software of NI ELVIS that allows students to design their
own graphical user interface in conjunction with the hardware features offered
by ELVIS such as acquiring and producing analog signals in order to verify
the voltage transfer characteristic curve, dc sweep, frequency response or to
characterize the performance of electrical and electronic circuits.
