BASED upon the lecturing experience of the author, this book presents an outline of the theory of the operation and design of thermionic valve circuits in a form suitable for university students during the final year of their degree course in electrical engineering. The treatment is confined to a consideration of the principles of the use of valves in their various forms in radio transmitters and receivers, and no attempt is made to describe how the different functions are realized in practice. While it is assumed that the reader has a knowledge of alternating current theory and the associated mathematics, a short summary of the vector algebra required for this subject is given in the first chapter. Subsequent chapters deal with the valve, and its use as an amplifier, oscillator, detector, frequency changer and modulator. The treatment throughout the book is very clear and straightforward, and appears to be almost entirely free from errors or misprints.
