Anderson and Johannesson, professors of digital communications and information theory, respectively, at Lund University in Sweden, introduce the field of information engineering to second-year students in information and communication technology programs, covering the nature, storage, transmission, networking, and protection of information. Preparation in mathematics (specifically, calculus, complex variables, and elementary probability) and physics (electromagnetic waves and DC electrical circuits) is assumed. For those who need a review, mathematical appendices and a chapter devoted to core mathematical techniques of the discipline are included.
