Introduction to Electron Tubes

Course No. E-4007

Credit: 4 PDH

Course Fee: $115.80 Purchase course

Subject Matter Expert: A. Bhatia, Mechanical Engineer

 

Overview

An electron tube is a device used for the processing of electrical signals.

Although solid state semiconductors have replaced the electron tubes in most applications, there are still niche applications where electron tubes not only continue to see practical use, but perform their respective tasks better than any solid-state device. For example, tubes are still used in some high-power amplifiers, especially at microwave radio frequencies and in some hi-fi audio systems. There are many die hard hi-fi enthusiasts who are faithful to the electron tube devices because the output power from the tubes has better audio quality, more fidelity and has less inherent distortions. Other items that still use electron tubes are televisions, radios, welders, test equipment, communication equipment and many others.

In general, the solid state devices reign in areas where compactness and low power consumption is a factor, but will lose out to the electron tubes where fidelity is the key factor.

This 4-hour course provides a basic understanding of Electron Tubes, explaining the basic theory, evolution and applications. The course is based entirely on Naval Education and Training Materials (NAVEDTRA 14178), Electricity and Electronic Training Series; Module-6 and covers Chapter 1 titled "Introduction to Electron Tubes".

The student must take a multiple-choice quiz consisting of twenty (20) questions at the end of this course to obtain PDH credits.
