For courses in Digital Communications.Exceptionally accessible, this book presents the often“difficult” concepts of digital communications in aneasy-to- understand manner—without diluting themathematical precision. Using a student-friendlyapproach, it develops the important techniques in thecontext of a unified structure (in block diagramform)—providing organization and structure to a fieldthat has, and continues, to grow rapidly, and ensuringthat students gain an awareness of the “big picture”even while delving into the details (the mostup-to-date modulation, coding, and signal processingtechniques that have become the basic tools of ourmodern era). It traces signals and key processing stepsfrom the information source through the transmitter,channel, receiver, and ultimately to the informationsink.
