Electronic Engineering Applications of Two-Port Networks aims to present the method of developing two-port theory to form the basis of a course on linear electronic systems. This book specifically presents topics on small-signal parameters; two-port models; small-signal analysis of the common-emitter amplifier; and general analysis of small-signal amplifier performance. A chapter is devoted to discussing topics on tandem connections of two ports, which is followed by exercises on matrix reduction. This text also tackles basic feedback connections, feedback amplifiers, and feedback oscillators. The application of the feedback systems is then examined. This book concludes by explaining the capacitive effects on transistor performance. This text will be beneficial to students and experts in the field of electronics.
