We present a procedure for computing the convolution of (analog-time) exponential signals without the need of solving integrals. The procedure is algebraic and requires the resolution of a system of linear equations. The method can be applied to find the impulse response of a linear time-invariant (LTI) system modeled by an ordinary differential equation and also to compute the solution of an ordinary differential equation with constant coefficients. We believe this technique can be useful for the analysis of LTI systems in time domain, since it is conceptually simple and can be easily implemented as algorithms in software packages like Scilab and/or Matlab.

Tracing the characteristic I-V curve of any photovoltaic device is the essential experiment that allows us to obtain reliable information about its state and behavior. Therefore, it must be part of the practical content in any Bachelor's, Master's or PhD degree that teaches the students in the photovoltaic systems engineering field. This paper presents the progress-achievements of two research groups -from Argentina and Spain- in the design of electronic prototypes or ad-hoc systems that carried out this experiment and which have subsequently been integrated into teaching practices. In addition, this knowledge has been incorporated into the research area in which the groups are involved.

Mobile applications have experimented a huge evolution in the last years. These applications are already an important tool in our daily life. From the point of view of the penetration of this mobile technology in the different scales of the society, university students are one of the main users of this mobile technology. For this reason, this work proposes a learning mobile application entitled EnjoyCircuits for Fundamentals of Electric Engineering of the Industrial Technology Engineering Bachelor. This mobile application is a learning tool based on the resolution of quick problems of circuit theory. With EnjoyCircuits students can do a dynamic review of the Fundamentals of Electric Engineering anywhere and anytime. Moreover, they can compete with other users in the EnjoyCircuits ranking.

Since the engagement of Universidad Nacional de Rosario (UNR) in the VISIR+ Project, several courses in the career of Electronic Engineering (EE) have incorporated experiments with electronic circuits based on VISIR remote lab. Three educational implementations in courses of the career of EE at UNR are introduced in this paper. Evaluation results are also discussed. Beyond potential adjustments, results are satisfactory and they encourage the continuity of these three implementations.

Master courses need to have a practical element, applying already known concepts to concrete problems. In this paper, the design and manufacturing of a radio link using APRS protocol over AX.25 will be presented as coursework during several lab sessions. The aim is to create a system that is able to poll data from several sensors and send them wirelessly with a software implemented signal generator in a microprocessor.

With the emergence of Internet of Things (IoT), appears the necessity of a protocol to handle the data flow of all the smart devices. HTTP (Hypertext Transfer Protocol) is the most used protocol. But, in recent years, new protocols are emerging. Nowadays, the Message Queue Telemetry Transport (MQTT) is one of the most used protocol within IoT, due to its low power and bandwidth consumption. This work presents the implementation of an MQTT protocol into LabVIEW platform providing a powerful tool to assess students training into novel protocols and applications under the IoT paradigm.

The Project Based Learning (PBL) is a teaching method in which students gain knowledge and skills by working for an extended period of time to respond to a challenge. This methodology is being applied to the subject of Radiofrequency carried out by the students of Telecommunication Systems and Communication Electronics Engineering degrees at the School of Engineering (Tecnun) of the University of Navarra. This subject is devoted to the design of the analog front-end of transceivers for wireless communications. As part of the subject a project is included, in which the students are asked to design, simulate build and validate a LTE receiver (Rx) at the 800-MHz band.

Teaching and learning Operational Amplifiers (OpAmps) in electronic engineering courses is a requirement, since they are a type of integrated circuit widely used for implementing simple or complex circuits. As a contribution to improve the way this integrated circuit is included in electronic engineering courses’ curricula, it was designed and implemented a reconfigurable and expandable kit to teach electronic circuits based on the OpAmp uA741. Able to run in a PC, the kit comprises a software application locally interfaced with a hardware platform. This platform includes a circuit with the OpAmp uA741 able to be reconfigured according to a set of parameters defined by a software application. Besides the reconfiguration capability provided by this kit, it also enables the establishment of automatic connections for measuring or applying signals to a reconfigured circuit, plus the ability to simulate the same or other OpAmp-based circuits. This paper provides an overview about the OpAmp uA741 and about its relevance in engineering education. Features and functionalities provided by the kit is described. At the end, supported by a technical demonstration of the kit in an international conference, some teachers’ opinions about their perceptions concerning its adoption in a real educational scenario are presented.

In the process of innovation of a technological product, the involvement of the disciplines is as necessary as the technological literacy of the team members. In fact, it is well known that the communication problems related to the lack of technological literacy hinder disruptive innovation. A methodological tool, Common Understanding Area (CUA) is presented, which is useful in the teaching field; as an individual instrument of learning; as an electronic product design guide; as a resource to structure the information; as a tool for communication and decision making; as a means of defining product specifications; and as a guide for the evaluation of concepts. Based on a long-term assessment with students of different degrees in engineering, the improved methodological tool is presented, now also transferred and validated in the professional field
