The design and servicing of the transistor circuit is more compli-cated than that of the vacuum tube, because transistor input and output circuits are never inherently independent of each other.

In this book we have attempted to clarify some of the basic theory of audio amplifiers so that the reader will be better able to design his own or service commercial audio amplifiers.

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.

This transistor consists of two electrodes (emitter and collector) which which make contact with a germanium pellet, and a third electrode (the base) which is soldered to that pellet.

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

For many years, the atom was considered to be the smallest particle of matter. It is now known that the atom is composed of still smaller entities called electrons, protons, and neutrons.

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.
