LEARNING OUTCOMES:
The fundamental purpose of this course is to provide students the necessary knowledge concerning the practical aspects of the use of measuring instruments, assembly of circuits, and the limits of the most common components and integrated circuits. It is important to observe, that the objectives of a normal course of electronics are to some extent different from those of this course. In fact, generally the goal is basically the understanding the operation of the various circuits proposed. For the experimental electronics course, on the contrary, the fundamental purpose is the synthesis or the project. In other words, choosing the right components of a circuit so that it behaves in the way you want.

KNOWLEDGE AND UNDERSTANDING:
Understanding of the practical aspects necessary for using the most commonly used measuring instruments, basic electronic configurations, and the most used integrated circuits.

APPLYING KNOWLEDGE AND UNDERSTANDING:
Ability to use the introduced measuring instruments, to design and to implement the electronic circuits examined during the course.

MAKING JUDGEMENTS:
Education for an independent evaluation, as it is necessary for verifying, through measurements, the synthesized electronic circuits implemented during the course. Furthermore, the reasoning is stimulated for the identification of all those errors in which the student may incur in phase of synthesis, implementation and measurement.

COMMUNICATION SKILLS:
The communication between the learner and the teacher is stimulated and refined during the course, as there is ample room for questions from students who need to know how to combine the theoretical and practical aspects of the proposed experiments.

LEARNING SKILLS:
The course is based on learning a series of preparatory elements. This requires the learning of a certain number of notions necessary to solve the experiments of the next lesson.

SYLLABUS

General concepts related to the use of measuring instruments present in the laboratory (multimeter, power supply, signal generator, oscilloscope).

COMMUNICATION SKILLS:
Students are invited to describe technologies in a proper technical way and with an adequate technical speech.

LEARNING SKILLS:
