Learning Outcomes of the Curricular Unit:
The main objective of this course is to provide the student with fundamental and practical knowledge about the theory of electrical and electronic analog electronics circuits, both in CC and AC, as well as to provide the student with important knowledge about the foundations of the electronic systems, including practical knowledge with measurement instruments and real electronic components gained in laboratory sessions.
At the end of the module a student will be able to:
- Describe the purpose of a resistive or reactive circuit and identify its components;
- Analyze and develop an electronic circuit using methods based on Kirchhoff’s Laws: Superposition, voltage and current dividers, Thévenin and Norton equivalents and Nodal Analysis.
- Explain how reactive circuits work in AC using phasor techniques to analyze and implement them.
- Propose and implement electronic circuits in experimental laboratory classes using breadboards, resistors, generators, capacitors and inductors.

Demonstration of the Syllabus Coherence with the Curricular Unit's Objectives:
The syllabus presented before covers the essential and consistent areas of knowledge required to achieve the objectives set out above, as the main topics included in the program, such as: foundations of current, voltage, power, methods for the analysis of resistive networks, reactive networks analysis, AC networks analysis and laboratory projects, cover the main aspects of study that enable students to calculate and implement resistive and reactive electronic circuits, as well as analyze and assemble DC and AC electronic circuits.
Teaching Methodologies (Including Evaluation):
The methodology of teaching and learning is expository, interrogative and demonstrative. Drawing on problem solving and study geared to allow the interpretation of fundamental principles of analog electric and electronic circuits both in DC and AC. Practical classes are based upon experimental protocols. The method of assessment comprises two components:
The evaluation of the theoretical component includes:
• 2 individual written tests (25% each, 50% of final grade).
The assessment of laboratory practical component includes:
• 4 practical Experimental Works in Laboratory classes/Technical reports, developed in a group (20% of final grade).
• 1 practical test for individual assessment (25% of final grade).
• The student's performance, including attendance, technical performance, active participation in class and capacity to solve problems as observed during the laboratory classes (5% of final grade).
Demonstration of the Coherence between the Teaching Methodologies and the Learning Outcomes:
The proposed methodologies are consistent with the objectives set for the course since they rely on the interpretation of the theory and practical application of the analog circuit analysis concepts studied, establishing a parallel between the theory and the practice applied to real problems of analysis and assemblage of analog electronic circuits, thereby helping students develop their ability to apply such techniques in the analysis and development of analog electric and electronic circuits used in Computer Systems Engineering.
