Introduction to Telecommunications

Telecommunications, Electronics and Communications Systems
  • ApresentaçãoPresentation
    This course, in the area of Telecommunications, is where students come across, for the first time, with the fundamental concepts of communication theory and its applications in analog and digital communication. It introduces elementary notions of spectrum and bandwidth to allow the analysis of the various types of communications systems. It also addresses applications of analog and digital modulations, as well as guided transmission systems.
  • ProgramaProgramme
    1. Introduction • Model of a telecommunications system • Notions of information, message and channel   2. Signals in time and frequency • Examples of signals in time • Notions of spectrum, power, phase and bandwidth • Communication channel: Characteristics, information propagation; notions of noise and inter-ference   3. Transmission Passes Bandwidth • Introduction to antennas (elementary notions, types, gain and directivity) • Applications with analog modulations, typical transmitters and receivers: AM (DSB, SSB, VSB, DSB-SC) and FM   4. Digital Broadcasting • Notions of sampling and quantization • Source coding (information, entropy, Huffmann coding) • Applications with digital modulations (bandpass): ASK, FSK, PSK, QAM   5. Guided transmission systems • Applications of Copper / Coaxial Cables (copper pairs, coaxial cable) • Fiber Optic Applications (elementary notions, fiber types, attenuation, dispersion, types of fiber, cables and connectors, OTDR, fiber optic links)
  • ObjectivosObjectives
    The main objective of the course is to transmit to students the basic concepts of telecommunications as well as to present the main applications and components of the systems. One intends to: - Introduce the notions of signals in time and their spectrum, to address the problems of communication channels. - Introduce the types of antennas, and their applications in elementary analog modulation systems, in order for the student to understand the characteristics and fundamental differences between them. - Present the elementary notions of digital transmission such as quantization, and source coding, as well as examples of the most used digital modulations, training the student for the different characteristics of these systems. - Finally, acquire elementary knowledge about guided transmission systems, such as copper pairs, coaxial cables from the perspective of their fundamental components
