Objectives

The main objective of the course is to provide students with training on complementary topics of electric circuit analysis, not covered in previous courses. Students first learn the concepts associated to the techniques of modeling two-port linear circuits and analyzing electric circuits built with two-port building blocks. Next chapter will introduce them to the ideal operational amplifier and how to analyze basic common circuits based on this device (amplifiers, active filters). This chapter also introduces the analysis of the frequency response of linear circuits in sinusoidal steady-state. Then, they learn how to analyze the step response of first- and second-order circuits (RC, RL and RLC). In the last chapter the students are introduced to the (ideal) diode as a first non-linear device and they learn how to analyze basic circuits involving diodes, using simplified models.

Learning outcomes and competences

After attending Circuits II, the students will be able to analyze circuits modeled as diports or associations of linear diports, as well as to determine (analytically and experimentally) the sets of parameters that describe a diport circuit. They will gain the competences to analyze and design simple circuits built with operational amplifiers, based on the simplified model of the ideal operational amplifier. They will also be able to represent and interpret the frequency response curves of linear circuits, operating in sinusoidal steady state. Complementing the subjects taught in previous courses, they will be capable to analyze the step response of 2nd-order RLC circuits (series and parallel), and to calculate the parameters that lead to a certain type of response.
The topics addressed in the last chapter will give the students the ability to analyze simple non-linear circuits built with diodes and the other devices studied in the course (eg. the operational amplifier).

The strong laboratory component constitutes an excellent opportunity to consolidate their knowledge about the analysis of electrical circuits and enhance their practical skills of using the test and measurement equipment typical found in an electrical engineering work bench.

Teaching methods and learning activities

Teaching makes use of theoretical and practical (lab) classes. In theoretical classes (1.5h), lecturing of the subjects takes place, whenever possible accompanied by resolution of illustrative examples. Practical classes (2h) allow the students to apply techniques for experimental verification of the functioning of electrical circuits illustrating the topics presented, and also to consolidate their skills with the tools and measurement instruments for electric systems, with emphasis in the oscilloscope. These classes include the resolution of exercises on the topics taugth in the theoretical classes.

Eligibility for exams

The students must attend at least 75% of the laboratory classes and participate in all the grading activities.

 

Calculation formula of final grade

The final grade (NF) will be computed based on the grade obtainmed in two mini tests (MT1 and MT2), the evaluation of the laboratory exercises (NL) and onthe grade of a final exam (EX):

NF =  0.15 * MT1 + 0.15 * MT2 + 0.2 * NL + 0.5 * EX

The laboratory grade NL includes the evaluation of the individual performance. The two minitests will be focused on the laboratory experiments done in the pratical classes and the final exam will address the subjects taught in the theoretical classes.

In order to obtain a passing grade it is necessary to have a final grade NF equal or superior to 10 points, a minimum grade of 50% for the sum of the minitests and laboratory grades (MT1+MT2+NL) and a minimum of 40% (8 points) in the grade of the final exam.

Examinations or Special Assignments

None

Internship work/project

None

Special assessment (TE, DA, ...)

It is the same as for regular students. Even though working students may be exempt from attending the practical classes, they are expected to take the two minitests and do a set of laboratory exercises equivalent to the exercises done by the regular students.

 

Classification improvement

The grade of the final exam can be improved by taking the 2nd exam ("recurso"). The grades obtained in the two minitests and laboratory classes can be improved by repeating these evaluation activites in the next edition of the course.
