Intended learning outcomes (Knowledges, skills and competencies to be developed by the students)

This Curricular Unit contributes to the acquisition of skills in the analysis of telecommunications circuits and systems, knowledge and explanation of the theory associated with electric and magnetic fields, design, implementation and maintenance of communication systems involving different transmission media and explanation of the principles of operation of telecommunication systems embedded circuits.
This Curricular Unit allows further development of skills in signal processing and in the interpretation of uncertainties inherent to the measurement of physical quantities.

Syllabus

The communication system. Modulation and coding.
Quadripoles and transmission units. Noise.
System analysis in time and frequency domains: linear systems, impulse response, transfer function, complex frequency, phasors and line spectra, periodic signals and average power use of series and Fourier Transforms in circuit analysis, convolution theorem.
Ideal/non-ideal sampling procedure. Sampling theorem, time/frequency analysis.
Propagation fundamentals. Free-space propagation, in the presence of the earth and atmosphere. Long, medium, short and ultra-short waves. Noise in communication systems. General concepts of transmission lines and antennas.
Analog modulation techniques: AM, DSB, SSB, VSSB, AM, FM, FM-Stereo.

Demonstration of the syllabus coherence with the UC intended learning outcomes

This Curricular Unit addresses key issues in the Telecommunications area, as exemplified by the study of quadripoles, transmission units, time/frequency analysis and sampling, therefore, giving the student a solid framework for the analysis of signals, circuits and telecommunication systems.
The study of electromagnetic wave propagation and modulation techniques gives the students a set of skills that allows, in a first approach, to acquire skills in the design, implementation and maintenance of telecommunications systems.
Throughout this course the student acquires knowledge regarding the identification and explanation of the uncertainty in the measurement of physical parameters in real context telecommunication networks.

Teaching methodologies

Teaching Methodology:
Theoretical/practical classes where composed of a theoretical explanation of main concepts and discussion of real world applications, together with the resolutions of exercises.

Evaluation Methodology:
Continuous (option):
(i) Two examinations are carried out.
(ii) The final grade (CT) is the average of the marks obtained in both examinations.
(iii) The minimum grade in each examination is 7.0 values.
(iv) Gets approved the student who obtains a grade greater than or equal to 9.5 values in the average of both examinations.
FINAL GRADE:
The final (CF) grade is obtained as follows:
CF = CE (or CT if that was the option) + ASSID
where CE corresponds to the grade of the final examination (if applicable) and ASSID is evaluated according to:
The student attended [70-80 [% of classes - 1.0 values
The student attended [80-90 [% of classes - 1.5 values
The student attended [90-100]% of classes - 2.0 values

Demonstration of the teaching methodologies coherence with the curricular unit's intended learning outcomes

The classes consist of a theoretical explanation of the main theoretical concepts, together with the study and discussion of real-life cases, thus enhancing the development of skills to analyze and solve real-life cases. The practical component is based on problem solving oriented towards the application of theoretical concepts to real-life cases of analysis, design and implementation of telecommunications systems.
