Objectives
Objectives
The principal 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.

Teaching methodologies and assessment
Teaching methodologies and assessment
The teaching methodology is divided into two components: (1) A strong theoretical component, where the fundamental concepts are lectured, and application problems solved; (2) Practical projects designed to illustrate the lectured concepts and promote the acquisition of computation skills. The evaluation components are:
Theoretical evaluation (70% of the final grade):
- Two written tests, encompassing all the subjects taught in the lectures or exams in the dates stated in the general regulations
- Oral exam (from which students with high leves of attendance and participation are exempt from)
- Minimum classification: 10.0 points
Practical assignment (30% of the final grade):- A set of practical mandatory assignments, defined by the teacher, available in all the dates stated in the general regulations
- Minimum classification: 10.0 points
