Introduction

In this subject, the theoretical and practical foundations necessary to work with circuits and electronic systems are received. From the simplest passive components to transistors, operational amplifiers and their applications. This knowledge is being worked in parallel with the necessary mathematical tools oriented to the analysis of circuits, such as; resolution of matrices, differential equations and Laplace transform. From the practical point of view, the students will work in the electronics laboratory where we will practice the implementation of the most representative circuits studied in this subject.

Teaching and learning activities

In person

TRAINING ACTIVITYMETHODOLOGYCOMPETENCES
Project-oriented learning is a method based on experiential and reflective learning in which the research process on a particular subject is of great importance. The aim is to resolve complex problems based on open solutions or tackle difficult issues that allow new knowledge to be generated and new skills to be developed by students.
Lectures are the setting for: learning and managing the terminology and language structures related to each scientific field. Practicing and developing oral and written communication skills. And learning how to analyse the bibliography and literature on Bioengineering. Using guidelines to identify and understand the main ideas during lectures. This academic activity has been an essential tool in education since it first began and should have a significant presence within the framework of this degree programme.
Reading texts with the aim of engaging critical thinking plays a fundamental role in learning for citizens who are both aware and responsible.
An activity for outside the classroom. This activity means students can allow their knowledge to settle and rest, which is always necessary before beginning a new task.
The professor sets out exercises and problems, helps students to progress in terms of the engineering process the design involves, and guides the student, thus partial goals are achieved that facilitate the incorporation of the theoretical knowledge acquired.
Practical classes allow students to interact at first hand with the tools they will need to use in their work. In small groups or individually practical demonstrations will be carried out based on the theoretical knowledge acquired during the theory classes.
In theory classes the fundamental and scientific knowledge that forms the basis of the knowledge and rigour that engineering studies require must be established.
This teaching method is based on reflection, it can provide students with useful knowledge and skills to tackle problems efficiently in a shorter period of time.
Individual work, involving study, the search for information, data processing and the internalisation of knowledge will allow students to consolidate their learning.

Important considerations:

  1. Plagiarism, copying or any other action that may be considered cheating will be zero in that evaluation section. Besides, plagiarism during exams will mean the immediate failing of the whole subject.
