Abstract

DIGITAL COMMUNICATION AS THE FIRST COURSE IN UNDERGRADUATE TELECOMMUNICATION ENGINEERING TECHNOLOGY PROGRAM Abstract The telecommunication and networking industry has undergone transformation from analog to digital in the recent past on a very big scale but the classroom education has lagged behind. Computers have come in front of all communication interfaces and the analog modulation and demodulation in amplitude, frequency and phase now have only conceptual values. There is a need for a first course that not only teaches basic concepts of telecommunication but also the digital communication principles and practices. The proposed course combines the fundamental concepts of frequency spectrum of signals and noise, multiplication of signals, filtering, oscillators and the voltage control of their frequency, phase locked loop, frequency synthesis and conversion, antenna analysis and design with the concepts of bandwidth of digital signals, analog to digital conversion, multiplexing of digital signals, coding, digital modulation, and multiple-access communication techniques. In this course, emphasis is put on design and simulation of digital transmitter and receiver engines, which is shown below, interjecting the techniques of over-the-Internet communication, and the introduction of Internet of Things (IoT) to effect long distance monitoring and task execution. As an approach for application, a small project is also assigned to students so they select their own interesting topics to build. Then, they give us a presentation at the end of the semester.

Abstract 
 
The telecommunication and networking industry has undergone transformation from analog to digital in the recent past on a very big scale but the classroom education has lagged behind. Computers have come in front of all communication interfaces and the analog modulation and demodulation in amplitude, frequency and phase now have only conceptual values. There is a need for a first course that not only teaches basic concepts of telecommunication but also the digital communication principles and practices. The proposed course combines the fundamental concepts of frequency spectrum of signals and noise, multiplication of signals, filtering, oscillators and the voltage control of their frequency, phase locked loop, frequency synthesis and conversion, antenna analysis and design with the concepts of bandwidth of digital signals, analog to digital conversion, multiplexing of digital signals, coding, digital modulation, and multiple-access communication techniques. In this course, emphasis is put on design and simulation of digital transmitter and receiver engines, which is shown below, interjecting the techniques of over-the-Internet communication, and the introduction of Internet of Things (IoT) to effect long distance monitoring and task execution. As an approach for application, a small project is also assigned to students so they select their own interesting topics to build. Then, they give us a presentation at the end of the semester.
