Digital and Analog Communication SystemsWiley, 28 thg 9, 1979 - 600 trang Provides a detailed, unified treatment of theoretical and practical aspects of digital and analog communication systems, with emphasis on digital communication systems. Integrates theory—keeping theoretical details to a minimum—with over 60 practical, worked examples illustrating real-life methods. Emphasizes deriving design equations that relate performance of functional blocks to design parameters. Illustrates how to trade off between power, band-width and equipment complexity while maintaining an acceptable quality of performance. Material is modularized so that appropriate portions can be selected to teach several different courses. Includes over 300 problems and an annotated bibliography in each chapter. |
