COMM 571 - COMMUNICATION TECHNOLOGIES

Instructor:Dr. A. Michael Noll, Professor
Term: Spring 2001
Technology has become extremely pervasive in the modern world. Technologies basic to computing and to communications enable an exciting variety of novel products and services with great impacts both on consumers and on the very structure of the communications industry itself.
It is essential that people working in all aspects of the communications field be literate and knowledgeable in the various electronic technologies and engineering concepts that are basic to modern communications systems and products. This technology literacy is necessary to facilitate meaningful communication with the engineers responsible for designing these systems and products. Furthermore, various evaluations, trade offs, and decisions will be better made if the technological aspects of these systems and products are better understood and appreciated.
The objective of the course is to provide the students with an understanding of the various electronic technological and engineering concepts basic to modern communications systems and products.
The course is designed to give a thorough treatment of the technologies that are basic to modern communications products and systems. The treatment is broad with a technical depth adequate for non-engineers. Appropriate mathematical descriptions, along with explanations of the mathematics as needed, will be utilized where necessary to facilitate an understanding of the technology.
The course begins with the concept of simple harmonic motion which is used to develop sinusoidal waveforms and the Fourier expansion of a waveform. Frequency and spectra are then described. Alternating and direct current electrical circuits, voltage and current, and circuit elements are explained. The concept of frequency and time multiplexing is developed and applied to amplitude, frequency, and pulse modulation. The process of converting an analog signal to its digital representation are explained along with its application to carrier systems and the and the compact disc.
The objective of most of the content of the course is to demystify technology and to illuminate the basic concepts fundamental to modern communication systems.
No technical knowledge is required. However, a rudimentary knowledge of basic arithmetic would be helpful, although all mathematical techniques used in the course are thoroughly explained.
The final grade will be determined from quizzes. A total of four quizzes will be given. Class participation and assignments will also be considered, particularly in borderline cases.
Only the highest standards of ethical conduct will be tolerated in this course. Accordingly, any student responsible for any violations of ethical conduct will receive a failing grade for the course and the incident will be reported to the School and the University with a recommendation for the imposition of additional sanctions, such as suspension form the Annenberg School and from the University. Unethical conduct includes such actions as plagiarism, cheating on examinations, fabrication, and purchasing papers or other assignments.
