Laboratory sessions
Full development process of a electronic filter:
1) Design and simulation of the filter. Component’s election.
2) Design of filter’s printed circuit board (PCB).
3) Fabrication of filter’s printed circuit board.
4) Assembly of filter’s printed circuit board.
5) Test of filter’s printed circuit board.
At the end of the course, the student must submit a single report collecting the results obtained in the laboratory sessions. This report will have a maximum extension of 20 pages. Besides, the results will be synthetically presented also in DINA3 poster format.
Methodology
Methodologically, the subject is proposed in a bimodal format:
In the first part of the subject, devoted to the introduction of concepts and design techniques of analog and digital filters, the student will work in an autonomous way with the support of the materials published in Campus Virtual, in person/guiding theory sessions and sessions for problems resolution.
In the second part, devoted to the fabrication technology, theory and problems resolution sessions will be carried out through master classes.
In the laboratory sessions, the student will practice the concepts acquired in both parts of the subject.
In general, a Moodle’s classroom, accessible through CAMPUS VIRTUAL (CV), will be used as a communication tool of news and as a repository of all the material in electronic format needed to follow the subject.
Annotation: Within the schedule set by the centre or degree programme, 15 minutes of one class will be reserved for students to evaluate their lecturers and their courses or modules through questionnaires.

Assessment
a) Process and programmed evaluation activities
The subject will be evaluated through the following activities:
- EP1: Partial Exam 1. Exam of part 1: Technological processes. It consists of a theory section and a problems section. 37.5% of FINAL MARK.
- EP2: Partial Exam 2. Exam of part 2: MOS transistor. It consists of a theory section and a problems section. 37.5% of FINAL MARK.
- LABINF: Laboratory sessions report (report version 20 pages). 12.5% of FINAL MARK.
- LABPOS: Laboratory sessions report (poster version). 12.5% of FINAL MARK.
The accomplishment of ALL these activities enables the continuous evaluation, as long as the mean mark over 10 obtained from the two exams is equal or higher than 4.5.
The activities with a second opportunity are:
EP1 and EP2, as indicated in section c).
The activities with NO second opportunity are:
LABINF and LABPOS.
To enable the evaluation of the LABINF activity it is necessary:
1) To attend ALL laboratory sessions (an absence proof will be required).
2) To submit both reports before deadline.
SUMMARY:
EXAM MARK = EP1_MARK*0.5 + EP2_MARK*0.5
LABINF MARK = LABINF_MARK*0.5 + LABPOS_MARK*0.5
If EXAM MARK > 4.5 then:
FINAL MARK = EXAM MARK*0.75 + LABINF MARK*0.25
If EXAM MARK < 4.5 then:
FINAL MARK = EXAM MARK
ALL marks in the previous expression are considered over 10.
b) Evaluation activities programming
The calendar of the evaluation activities* will be published through the Moodle’s classroom (CAMPUS VIRTUAL) during the firsts semester’s weeks. In any case, it is foreknown that:
-EP1 will take place at mid semester: last week dedicated to Part 1 (just before or after Easter).
-EP2 will take place at the end of semester: last week dedicated to Part 2 (just before resit exams period).
-The laboratory report, LABINF and LABPOS, will be submitted not later the resit exam*, following the procedure indicated in the Moodle’s classroom.
*The resit exams will be published in the Engineering School’s webpage (exams part).
c) Retrieval process
According to UAB regulations, the student can only participate in the retrieval process as long as he has fulfilled a set of activities representing at least 2/3 of the final mark of the subject. In the case of the present subject, this condition is only fulfilled if the student attends both partial exams.
The only retrievable activities are the partial exams EP1 and EP2, by means of a FINAL RESIT EXAM.
This FINAL RESIT EXAM consists of 2 independent parts corresponding to Part 1 (Filters) and Part 2 (Fabrication technology), each one of them with their own theory and problems sections (identical structure as partial exams), so that it is possible to retrieve the mark of one single part or the mark of both parts. Thus, the mark of each part, FINAL_MARK1 and FINAL_MARK2, substitutes the mark of the corresponding partial exam, EP1_ MARK and EP2_MARK, as long as the first one overcomes the second one.
Therefore, the FINAL RESIT EXAM will NEVER lead to a mark lower than the obtained through the partial exams.
SUMMARY:
EXAM MARK = MAX(EP1_ MARK ; FINAL_MARK1)*0.5 + MAX(EP2_ MARK ; FINAL_MARK2)*0.5
LABINF MARK = LABINF_MARK*0.5 + LABPOS_MARK*0.5
If EXAM MARK > 4.5 then:
FINAL MARK= EXAM MARK*0.75 + LABINF MARK*0.25
If EXAM MARK < 4.5 then:
FINAL MARK= EXAM MARK
ALL marks in the previous expression are considered over 10.
d) Marks review procedure
For each evaluation activity, it will be indicated (through Campus Virtual) place, date and time for the review with the teacher of the evaluation activity results. In this context, the student will be able to exhibit possible claims about the obtained mark, that will be analyzed bythe teacher. In case the student does not attend the review, any other review activity will be scheduled later.
e) Marks
A student will be considered NOT EVALUABLE (NA) if one of the two following conditions is satisfied:
a) He/she does not attend at least one of the two partial exams EP1 or EP2.
b) He/she does not submit the laboratory report LABINF
On the other hand, according to UAB regulations, among those students with a final mark over 9.0, a maximum number of Matrícules d’Honor (MH) corresponding to 5% (rounded by excess) of the total number of students can be granted. In case the number of students is below 20, 1 MH can be granted.
f) Student’s irregularities, copy and plagiarism
Without detriment of other disciplinary measures, it will be graded with a zero all the irregularities committed by the student that could lead to a modification in the mark of an evaluation activity. Therefore, copying, plagiarizing, misleading, letting copy, etc. in any of the evaluation activities will imply to fail the activity with a zero.
g) Evaluation of repeating students
As from the second enrollment, the student may ask to validate the laboratory mark (LABINF MARK) obtained in a previous course. In this case, it is not necessary that the student to notifies this fact to the teacher in charge of the subject.
