Electrical engineering is an exciting field through which we interface with the world using electrical signals. The book contains 32 Technology Briefs, each providing an overview of a topic that every electrical and computer engineering professional should become familiar with. Electronic displays, data storage media, sensors and actuators, supercapacitors, and 3-D imaging are typical of the topics shared with the reader. The Briefs are presented at a technical level intended to introduce the student to how the concepts in the chapter arc applied in real-world applications and to interest the reader in pursuing the subject further on his/her own. Technology Briefs cover applications in circuits, medicine, the physical world, optics, signals and systems, and more.
