Digital Electronics And Laboratory Computer Experiments

Science undergraduates have come to accept the use of computers as commonplace. The daily use of portable sophisticated electronic calculators (some of them rivaling general-purpose minicomputers in their capa bi li ti es) has hastened this development. Over the past several years, computer assisted experimentation has assumed an important role in the experimental laboratory. Mini- and microcomputer systems have become an important part of the physical scientist's array of analytical instruments. Prompted by our beliefthat this was an inevitable development, we began several years aga to develop the curricular materials presented in this manual. At the outset, several objectives seemed important to uso First, insofar as possible, the experiments included should be thoroughly tested and error free. Second, they should be compatible with a variety of laboratory computer, data-acquisition, and control systems. Third, little or no previous background in either electronics or programming should be necessary. (Of course, such background would be advantageous. ) To satisfy these objectives, we decided to adopt a widespread high-level computer language, BASIC, suitably modified for the purpose. Furthermore, we have purposely avoided specifying any particular system or equipment. Rather, the functional characteristics of both hardware and software required are stipulated. The experiments have been developed using Varian 620 and Hewlett-Packard 2100 series computers, but we believe they are readily transferable to other commonly available computer systems with a minimum of difficulty.

Created to provide a safer and more cost effective lab environment, these innovative manuals introduce new methods to learning and understanding circuit analysis concepts by using Electronics Workbench to simulate actual lab experiments on the computer. Using the latest circuit simulation software, they allow for easy circuit modification, more extensive troubleshooting experiments, and more powerful computational tools. Readers work with circuits drawn on the computer screen and with simulated instruments that act like actual laboratory instruments. Circuits can be modified easily with on-screen editing, and analysis results provide fast, accurate feedback. The manuals provide extensive technical preparation for each interactive experiment, and a series of questions about the results of each experiment requires users to think about and to analyze the results of the experiments in more depth than is customary in other lab manuals. The manual examines diodes, bipolar transistors, field-effect transistors, operational amplifiers, amplifier frequency response, active filters, and oscillators. For individuals interested in fine tuning their knowledge of electronic devises using Electronics Workbench.

For Freshman/Sophomore level courses in Digital Circuit Design, Digital System Design, and Computer Engineering Technology. This book offers an easy-to-read, easy-to-follow approach to digital fundamentals through the use of Complex Programmable Logic Devices (CPLDs). The use of advanced logic device technology in an introductory digital course prepares students both for lab work in advanced courses as well as for using an industry-standard design environment.

The accompanying CD-ROM includes all of the troubleshooting circuits and all of the circuits needed to perform the experiments.
