Lehigh University

ECE 82 Sophomore Laboratory

Catalog description: An introduction to the fundamental laboratory instrumentation and measurement techniques of electrical and computer engineering. Experiments based on the fundamental concepts discussed in the prerequisite courses. Introduction to PSPICE and application of various computer aids to design and documentation. Discussions of electrical components and laboratory safety. Use of an engineering notebook and report writing.

Required or elective: required.

Credit hours: 1

Prerequisites: ECE 33 and ECE 81.

Textbook: Laboratory notes.

Course objectives:
Upon completing this course, students will

be able to use standard laboratory instruments
understand the electrical characterisitcs of circuit elements
design, implement, and evaluate basic electrical and electronic circuits
be able to use PSPICE simulations as design aids

Topics covered:

Use of multimeter, power supply, oscilloscope, function generator and protoboard.

Study of Thevenin equivalent circuits and transient behavior of first-order systems

Measurement and analysis of R-2R ladder circuits

Operational amplifier characteristics and performance

Magnitude and frequency response of filter circuits of 1^st and 2^nd order (low-pass, high-pass and band-pass)

Behavior of comparators

Characterization of TTL and CMOS (inverter and NAND) Logic Gates

Relaxation oscillators and clock generators

Operation of Binary Counters, dividers and decoders

Signal Conversion and recovery using D/A converter with A/D converter and reconstruction filter

Nyquist rate sampling, signal reconstruction and aliasing

Assessment: Lab reports are written and handed in for each of 6 experiments. Students also perform PSPICE simulations in advance for circuits explored in the laboratory unless no device model is available (in the student version) of the integrated circuit under investigation. Some simulations are turned in for homework and may also be used for comparison with laboratory results. Assessment is based upon quality, completeness and accuracy of the laboratory work and reports. Labs are graded and returned promptly so that grading feedback is incremental. There are no tests or quizzes and there is no final examination.

Class/laboratory schedule: One 3 hour laboratory session per week.

Relationship of course to ABET criteria (Criterion 3).

The course supports the following ABET criteria:

3(a) an ability to apply knowledge of mathematics, science, and engineering

This is accomplished through the use of mathematics to the analysis of electronic circuits.

3(b) an ability to design and conduct experiments, as well as to analyze and interpret data.

This is done through the six experiments set for this course.

3(e) an ability to identify, formulate, and solve engineering problems.

This is done through preparation and execution of the experiments of this course.

3(k) an ability to use the techniques, skills, and modern engineering tools necessary for engineering practice.

This is done through the use of the latest instruments necessary to study the circuits of the experiments.

Contribution of course to meet professional component (ABET criterion 4)

The course contributes to the following criteria

4(a) in providing university level mathematics and basic sciences with experimental experience appropriate to electrical and computer engineering.

4(b) in providing engineering topics, consisting of engineering sciences and engineering design appropriate to electrical and computer engineering.

This is accomplished by the student applying mathematical skills to understanding basic electrical and computer engineering concepts within the context of practical and meaningful experiments.
