Author Notes

After serving in the U.S. Army, Wayne Tomasi studied at Arizona State University, where he earned a degree in engineering. He continued with graduate work at that same institution. During his career, Tomasi has worked for six years as a communications engineer with AT&T, three years as a design engineer of biological test equipment, one year as a TV broadcast engineer, and one year as supervisor of the electronic communications department at Arizona State University. His background of practical experience is evident in the very accessible texts he has produced during 17 years as professor of electronics, first at the DeVry Institute of Technology in Phoenix and later at Mesa Community College. In addition to the books he has authored, he has also written five laboratory manuals. Tomasi is a man committed to his subject and to cultivating that same commitment in his students.
