A textbook introducing discrete linear devices and circuits and describing operational amplifiers and other linear integrated circuits. One feature is that the circuit diagrams indicate current with a polarized meter symbol rather than arrows, both to reflect the readings from an ammeter and to specify the relative current magnitude. Radio-frequency amplifiers and transducers are also considered. Solutions to some of the end-of-section exercises are provided at the end of each chapter. The glossary does not indicate pronunciation. No bibliography. Annotation c. by Book News, Inc., Portland, Or.
