✦ Synopsis


familiarity

with elementary electrical theory is assumed, but an excellent &sum6 which precedes the development of the subject provides the reader with a valuable introductory review which, while thoroughly modern, is in conformity with current practice.

The work is in three divisions with an appendix. In Part I, Theoretical Basis of Radio Measurements, are discussed the fundamentals of electromagnetism, the principles of alternating currents, radio circuits and damping. Part II, Instruments and Methods of Radio Measurements, contains a description and analysis of wave meters, condensers, coils, current measurement, resistance measurement and sources of high-frequency current.

Part III, Formulas and Data, deals with the calculation of capacity, calculation of inductance, design of inductance coils, high-frequency resistance and miscellaneous formulas and data. The appendix, in three parts, contains an account of the radio work of the bureau, a bibliography and a list of the symbols used.

Those who are acquainted with the high order of merit of the publications of the Bureau of Standards will not be disappointed in this timely work on the quantitative features of a subject of widespread interest.
