The electrical engineering curriculum in every university now includes either a one-semester or one-year course in communications theory and practice and/or communications engineering.An indispensable supplement to the standard texts used in those courses, this new edition of the classic Schaum's Outline has been thoroughly revised and updated to conform to the latest changes in the engineering curriculum. It now features new chapters on signals and spectra, signal transmission and filtering, information channel capacity, and error-control coding. It covers noiseless modulation theory, including amplitude and angle modulation, and includes expanded coverage of digital communications. It a lso features 430 fully solved p roblems.Hwei Hsu, Ph.D., is a professor and former chair of the Electrical Engineering Department at Fairleigh Dickinson University.
