Explains how analog voice becomes digital bits (PCM) and how those bits are shaped into electrical pulses (Line coding: NRZ, RZ, Manchester).
Digital signals can be regenerated perfectly even after suffering distortion.
To appreciate the depth of the textbook, it's helpful to know the background of its author. Dr. Ali Grami is not merely an academic but a seasoned engineer who has made significant contributions to the field. He earned his PhD in Electrical Engineering from the University of Toronto. His industry experience includes work at Nortel Networks, where he was involved in the research and development of North America's first digital cellular wireless system. He later joined Telesat Canada and was the lead researcher and principal designer of Canada's Anik-F2 Ka-band system, which is recognized as the world's first broadband access satellite system. Currently, he is an associate professor at the University of Ontario Institute of Technology (UOIT), where he has played a key role in developing its engineering programs. This unique blend of real-world engineering and academic teaching allows him to present complex concepts with practical, relatable insights.
