Circuit Theory Francesco Piazza
Basic mathematical knowledge (Math1, Math2, Linear Algebra or equivalent), basic Electromagnetic knowledge
KNOWLEDGE AND UNDERSTANDING:
To know and understand basic circuit theory concepts, applied to lumped linear time-invariant electrical circuits. In particular, to be able to analyze transient and steady state responses of these circuits, to compute powers and energies, to evaluate frequency responses and sensitivities to parameter variations.CAPACITY TO APPLY KNOWLEDGE AND UNDERSTANDING:
The student will be able to analyse in practice continuous-time non-directional circuits with particular reference to lumped linear time-invariant electrical circuits. Therefore, he will acquire the following main skills:
1. ability to use standard circuit analysis methods (nodal, loop);
2. ability to analyse 1-, 2- or multi port sub-circuits and their interactions inside the circuit;
3. ability to compute circuit responses in the time domain, Laplace domain and frequency domain;
4. ability to compute powers and energies in circuits;
5. ability to evaluate the sensitivity of different circuit designs to component variations.TRANSVERSAL SKILLS:
The student will acquire also the following general skills: the ability to use mathematical tools in a real world application field, the ability to model EM or non-EM phenomenon with the circuit theory approach, the ability to analyse a complex system as a set of interacting subsystems. The time constrained circuit analysis tests will contribute to make better judgements and to strengthen the ability to synthetize and communicate the obtained results. The large number of possible circuit schemes will force the student to develop better autonomous learning and analysis skills.
Introduction to circuit theory, electrical circuit model, analysis of circuits without memory, external representations of circuits, transformations and equivalences, time-domain analysis of circuits with memory, transformed-domain analysis, DC/AC steady state analysis, frequency domain analysis, sensitivity to component variations, power and energy, three-phase circuits, application examples.
Development of the examination
LEARNING EVALUATION METHODS
The evaluation process consists of two parts (to be accomplished sequentially):
Exam Part 1:
written test consisting of the analysis of 2 electrical LTI circuits in transient, DC steady and AC steady states (allowed time 3 hours).
Exam Part 2:
Written test consisting of 4 open questions on course topics (allowed time 90 min).
LEARNING EVALUATION CRITERIA
Exam Part 1:
evaluation of the completeness and correctness of the analysis, ability to apply in practice course notions and concepts.
Exam Part 2:
evaluation of knowledge level on course topics. To complete this part, the student must demonstrate a sufficient level of knowledge, i.e. at least 3 positive answers.
LEARNING MEASUREMENT CRITERIA
The evaluation is performed according to 30-point grading scale on each exam part. 16/30 is the minimum score to complete the fist part, 18/30 is the minimum score to complete the second part.
FINAL MARK ALLOCATION CRITERIA
The final mark up to 30/30 is computed as the average (integer rounded) of the marks obtained in the two exam parts. The minimum passing grade is 18/30. The cum laude attribution, which means a superior performance, is granted only if the student gets the maximum mark in both exam parts and demonstrates a superior level of interest and understanding on course topics.
