One of the most unfortunate features of the usual portable Geiger counter is the short life of the expensive high-voltage batteries.

This chapter deals with basic four-terminal' analysis in general, and the specific application of four-terminal network analysis to the transistor.

This transistor light control box will take your automobile one more step toward complete automation.

A battery is a low-impedence source of power. It is most efficient and economical when supplying low voltage at high current.

Ever since the point contact transistor was announced by the Bell Telephone Laboratories in 1948, a considerable effort has been directed toward the improvement of transistor manufacturing and circuit design techniques.

Transistors are finding new and ever-increasing uses. Some of the circuits in which transistors are being applied are well-known through prior employment in conjunction with vacuum tubes.

Test methods and specifications are necessary for the proper evaluation of transistors because they are temperature-sensitive devices whose characteristics and parameters vary over wide ranges.

There has been, and still is, a tendency on the part of electronics technicians and engineers to make comparisons between vacuum tubes and transistors.

The electrical ratings of transistors are generally given in terms of a few basic characteristics. Since these characteristics are, for the most part, different from those used to describe vacuum tubes or other electronic components, it is important that the electronic technician, student, and serviceman become familiar with them.

Transistors, important as they may be, represent only a part of a large group of semiconductor devices. Year: 1953
