Choice Review

Helms has compiled a collection of circuit designs and applications that have appeared in recent electronics magazines, in applications notes, and in databooks. These circuits cover a wide range of electronics technology. The descriptive material is minimal, but each circuit description includes type numbers or values for all significant components, and the original source of the circuit. This book may save the user a lot of time by obviating the need for literature research. Some of the broad topics included are active filters, amplifiers, antennas, audio, automotive, digital conversion, synthesis, optoelectronics, measurements, and modems; also treated are oscillators, power supplies, receivers, repeaters, single sidebands, telephone, teleprinters, television, test equipment, timers, transceivers, transmitters, and voltage regulators. Recommended for acquisition by technical libraries and academic engineering libraries.-S. Lapatine, College of Staten Island, CUNY
