ABSTRACT

The paper presents a laboratory development for measurement, analysis, design, and simulation of typical electric and electronic circuits using modern computer hardware and software. It shows computer measurement and data acquisition system using National Instruments (NI) LabView and NI-ELVIS, and gives methodologies for theoretical analysis and design of electric and electronic circuits using MathCad. It presents the development of a virtual laboratory using PSpice, and illustrates how Microsoft Excel spreadsheets and MatLab are used for data recording and/or result comparisons among measurements, theoretical calculations, and simulations. The paper shows the mechanisms and approaches developed for strong correlation between theories and hands-on experimentations using modern computer tools for the purpose of quality education of a laboratory course in electric and electronic circuits.

Index Terms – Education, laboratory, electric and electronic circuits, LabView, NI ELVIS, MathCad, PSpice simulation, Microsoft Excel spreadsheets, MatLab.

1. INTRODUCTION

Computers and microprocessors have changed a lot in the field of traditional Electrical Engineering (EE). They are also changing the traditional teaching styles in higher education. When digital computers as well as various software and hardware are used in laboratories and classrooms, they can provide much more effective and efficient ways in teaching and make many mathematical related engineering problems easy to understand.

The Circuits and Electronics Lab, a first semester junior EE laboratory course at Texas A&M University – Kingsville (TAMUK) draws on and correlates with the knowledge obtained by students from their sophomore and early junior level EE courses such as electric circuits and electronics. Traditionally, all of the lab experiments in this course were based on traditional equipments, devices, methods and techniques for measurements, data recording, and result analysis. This usually makes experiments time-consuming and inefficient, and therefore, greatly limits the effectiveness in the students’ understanding of fundamental concepts and theories from
