Summary
Motivation
The history of electronics has been inextricably linked with the growth of the communications industry. Electronic communication served as a major enabling technology for the industrial revolution. When scientists and engineers learned to control electricity and magnetism, it did not take long for people to realize that the electromagnetic force would enable long-range communication. Even though the basic science of Maxwell's equations was well understood, it took much longer for practical applications to fully exploit all the fantastic possibilities such as radio, television, and personal wireless communication.
At first only crude wires carrying telegraph signals were rolled out sending Morse code, digital signals at speeds limited by human operators. In this regard it is ironic that digital communication predates analog communication. Telegraph wires were laid alongside train tracks, making long-range communication and transportation a practical reality. Sending signals faster and further ignited the imagination of engineers of the time and forced them to study carefully and understand the electromagnetic force of nature. Today we are again re-learning and inventing new digital and analog communication systems that are once again compelling us to return to the very fundamental science of electricity and magnetism.
The topic of this book is the high-frequency electromagnetic properties of passive and active devices. For the most part, passive devices are resistors, capacitors, transformers, and inductors, while active devices are transistors. Most applications we draw from are high-frequency circuits.
