CE23: Understand the applications of electronic instrumentation.
CE24: Train to design analog, digital and power electronic systems.
CT2: That students have the ability to work as members of an interdisciplinary team either as one more member, or performing management tasks in order to contribute to developing projects with pragmatism and a sense of responsibility, assuming commitments taking into account count available resources.
The subject of Instrumentation is part of the subject of Analog Electronic Systems, which is taught entirely in the 3rd year of the Degree. In this subject use is made of the different techniques of analysis and electronic design, both analog and digital introduced in the previous subjects of electronics of the degree (Analog Electronics I & II i Digital Electronics II mainly) in order to be able to acquire and process data on physico-chemical quantities, thus designing and understanding the principles of Data Acquisition Systems (DAQs).
This subject has methodological and digital resources to make possible its continuity in non-contact mode in the case of being necessary for reasons related to the Covid-19. In this way, the achievement of the same knowledge and skills that are specified in this teaching plan will be ensured. The Tecnocampus will make available to teachers and students the digital tools needed to carry out the course, as well as guides and recommendations that facilitate adaptation to the non-contact mode.
This subject contributes to the achievement of the following learning outcomes specified by the subject to which it belongs:
-RA1: Analyzes application circuits of operational, linear and nonlinear amplifiers. (CE24)
-RA2: Know the structure and operation of industrial sensors. (CE23)
-RA3: Be able to limit the errors of the measurements. (CE23)
-RA4: Know the instrument interconnection buses. (CE23, CE24)
At the end of the course the student must be able to:
The course consists of 6 hours a week: 4 face-to-face theory in the classroom and 2 sessions scheduled for internships. Classroom work will be based on classes where the teacher will explain the concepts of theory, accompanied by multiple examples and problems following the Socratic heuristic method.
In the exercise resolution sessions, both individual and collective experimentation are proposed, working on both the approach and the final resolution of the same. The necessary tools will be given to be able to solve the set of these activities, although the student requires in an important set of occasions, to finish them outside the formally hours of class, being these the previously conceived within the frame of the hours of autonomous learning.
The activities of a practical nature will be carried out in the laboratory, understanding that the basic operation of the instruments that make up the generic bench is known.
This course, due to the situation generated by COVID, the theoretical sessions will be taught in online mode. With regard to the regulated practice sessions that require the student's presence in the laboratory, if applicable, work will be done simultaneously in several spaces in order to ensure that the conditions established by the safety protocols are met, establishing a dynamics of rotary assistance in the nominal laboratory (Laboratory # 1).

ACTIVITY 1: PRACTICES (20%):
[Linked to the achievement of Competences CB2, CT2, CE23 (RA2, RA3) and CE24 (RA1, RA4)].
-PRACTICE 1: ULTRASOUND SENSOR (1 Session):
- PRACTICE 2: OPTOELECTRONIC SENSORS (2/3 Sessions):
- PRACTICE 3: SPECIFIC SIGNAL CONDITIONING SYSTEMS (3 Sessions):
- PRACTICE 4: DAQ: DIGITAL SIGNAL ACQUISITION AND PROCESSING in MATLAB (3 Sessions):
(): The final number of internship sessions will depend on the schedule and pace of the internship group.
It will be necessary to make a report in groups of each one of the practices, that will finish with an obligatory section of conclusions which will correspond to the 20% of the report.
ACTIVITY 2: PROBLEMS (10%):
[Linked to the achievement of Competences CB2, CE23 (RA2, RA3) and CE24 (RA1)].
Two collections of problems corresponding to Blocks 1 and 2 of the subject are made available to students, which form part of the learning and achievement base of the subject together with the class notes. The resolution of the same will do, a part of form no presencial and the rest, in specific sessions of resolution of problems in the sessions of theory and that will use to evaluate this activity. (This activity will be done with notes).
ACTIVITIES 3 and 4: PARTIAL EXAMS 1 AND 2 (35% + 35%):
[Linked to the achievement of Competences CB2, CE23 (RA2) and CE24 (RA1)].
There are two exams that each consist of solving four problems. The second partial exam will include explicitly, the contents of the 2nd part of the subject and implicitly, some of the 1st part of the same (and evaluated in the context of the first partial).
The first exam will be held during the course on a day set at the beginning of the course and the second will be held on the date scheduled by the director of studies after the end of the class period and within the stipulated period of exams.
In case of confinement the following changes will be applied:
The final grade will be the weighted average of the grades of the assessable activities mentioned, as specified below:
PARTIAL EXAMINATION 1 (35%) + PARTIAL EXAM 2 (35%) + PRACTICES (20%) + PROBLEMS (10%)
It will be necessary to obtain a minimum mark of 3 in the two written tests, to be able to choose to apply the corresponding weighting.
If the average of the subject is less than 5, 20% of the qualification of practices and 10% of the qualification obtained in the component of problems will be maintained and a mechanism of recovery of the component of will be activated in parallel. theory, that will consist of the resolution of an Examination of Recovery of the global of the course and that will account for 70% of the total calculation of the same.
In case of passing the overall subject under this second assumption, the final grade of the subject will be limited to 5.
