This curricular unit, of the telecommunications field, is where the students first cross paths with the foundational concepts of communication theory, and its applications to analog and digital communication. Hence, knowledge of the previously lectured topics in Signals and Systems and Data Acquisition and Processing, are recommended. The skill set herein obtained are paramount for the design and development of data codification and compression algorithms (e.g., audio, video, text, etc.) as well as in other areas of communications and computer science.

Objectives
Objectives
The main goal is to transmit to the students the basic concepts of telecommunications, as well as to introduce the main mathematical and computational tools needed for their treatment. The plan is to: - Present the basics of analog modulations, pulse modulation and source coding. In this way the students will be able to understand, develop and design analog communication systems. - Develop a broad knowledge of concepts and principles of telecommunications, which permits the student to apply this knowledge to systems that are governed by the same principles. - Acquire the capability to analyze and manipulate signals and LTI Systems, represented in both the time and frequency domain, using the Fourier Transform.
