237 pages including index. Gilt writing on spine is hardly worn. Hinges intact. Corners and edges moderately worn. Normal bumping to corners, Spine ends faded but intact. Contents moderately yellowed. Spotting to rear flyleaf and back of page 237. This book was designed to fill a gap in the literature on vacuum tubes, viz., graphical constructions. By graphical constructions are meant those geometric manipulations by which are obtained solutions to problems on nonlinear circuits, particularly those involving vacuum tubes. Analytical derivations are often in the body of the text, as in the chapters on balanced amplifiers and on detection. Much of the material here is original, and a good deal of this appeared in the 'RCA Review' and in 'Communications.' However, in many instances the discussion has been expanded and revised, as in the chapter on balanced amplifiers. Chapters include 1. The Non-Linear Circuit Problem 2. Thermoionic Vaccum Tubes 3. Elementary Graphical Constructions 4. Reactive Loads 5. Balanced Amplifiers. 6. Detection 7. Misc. Graphical Constructions. Each chapter has its own bibliography. From the Radio Communication Series.
