Course Descriptions

0614-271 Telecommunications Fundamentals

A survey of and introduction to the structure and regulation of the telecommunications industry. The basics of data communications, telephony, switching systems, ISDN, multiplexing, and networks are introduced. Data communications components, codes and techniques are identified. Methods for selecting, implementing and managing a computer network or telephone system are reviewed.
(No prerequisite)

0614-464 Voice Communication Systems

Voice is perhaps the most basic form of communication and modern networks must continue to support high-quality voice communication. This course examines the basic characteristics of voice in both the time and frequency domain and shows on-line how these characteristics affect the requirements of communication networks. Both analog and digital representations of voice signals are considered, including advanced voice coding (e.g, G 729) for wireless and VoIP systems. The course covers baseband and carrier-based transmission of voice as well as Real Time Protocol (RTP) for VoIP. Signaling protocols for call processing for both circuit-switched and packet-switched communication are also covered. This course is similar to 0614-465, but it has no associated laboratory course and it requires a research paper. Students may not take both this course and 0614-465 for credit.
Prerequisite: 0614-271

0618-206 Computers and Their Applications

This course introduces students to the fundamental concepts and problem areas of computers and their applications through a survey of the major sub-areas of the field. Students will learn the nature of programming and how to create simple programs using HTML. Students will also spend time using Word, Excel, as well as other applications. Since this course is a combination of concepts of computers and applications, students will also study the history of computing, how computers are built, the Internet, automation and control systems, the future of computers, security and ethical and social issues associated with computers and their applications.
(No prerequisite)

Acceptable substitute for this course is as follows:

0692-250 Introduction to Computer Programming

Basic concepts and overview of computer science. The topics include historical development, algorithms, flowcharting and programming in BASIC. Exposure to hardware concepts, software concepts, binary and hex numbers and logic. Application of the computer to various disciplines. Not for computer science majors.
Prerequisite: High school intermediate algebra
