Learning methods in engineering education should evolve to take advantage of the progress of technology. Despite being one of the most important theorems of engineering, at undergraduate level the foundations of sampling theorem are usually oversimplified, whereas at graduate level its proof is frequently presented in the context of a rigorous mathematical framework. This paper presents an interactive approach to illustrate an amenable proof of the sampling theorem through example. Apart from its practical value as a learning tool, the proof captures some mathematical subtleties that can help to understand some more advanced concepts. The goal of this work is to show that learning the sampling theorem through an interactive example of its mathematical proof can be an enjoyable and insightful experience.

The subject of electromagnetic compatibility is a compulsory one, taught to students from electrical engineering and applied electronics study programmes. We present a comparative study between the current teaching method of shielding calculation and a new simulation-based teaching approach. In the academic year 2013-2014, the effectiveness of the new method was evaluated by analyzing the answers provided by the students to the items in a questionnaire along with their final lab test scores.

A new approach to teaching Communication Systems course is proposed, which is based on the use of animations as a complement to the lecture material. The animations are designed to visualize abstract mathematical concepts, related to modulation techniques and communication system analysis in presence of noise, and present these concepts to the students in visual and understandable form in the classroom. The animations have double purpose. They are to be used, firstly, by the lecturers during lecture presentations, and secondly, as an additional aid to the students to support their self-learning activity. The animations are developed on MATLAB platform. K E Y W O R D S abstract concepts visualization, animation, communication systems, modulation, noisy channel | INTRODUCTIONStudents' understanding of communication systems theory and practice may be enhanced by the use of related laboratories and tutorials. However, this enhancement might be limited due to the lack of deep understanding of theoretical concepts presented at the lectures. For this reason, the animations are developed and presented in this paper, which make a complementary part of lectures and are dedicated to the lecturers to support their explanations of abstract mathematical concepts. The animations for this purpose, to the best of authors' knowledge, have not been developed yet, except some similar animations based on Mathematica software, which were developed and dedicated to the engineers and students to capture the wave phenomena [4].One of the problems to consider in the design of the animations is the required operational time. Namely, the allotted time for an animation inside the lecture slot is strictly limited, because most of the lecture time is supposed to be dedicated to lecture material. In order to make the animation succinct, they are designed within a MATLAB environment with a graphical user interface (GUI) with minimized set-up and execution time. Therefore, the required time for an animation per lecture can be measured in minutes.The development of animations included these steps: Firstly, the modeling of abstract theoretical concepts or devices; secondly, the MATLAB implementation of these concepts and their visualization based on the developed GUI; and, thirdly, the use of animations in the classroom and doing survey of students to get a feedback about animations' efficiency. The structure of animations followed the general content of lectures in Communication Systems, including these topics: the basic signal analysis, modulation techniques, channel characterisation, communication systems with noisy channel, super-heterodyne receivers, frequency division multiplexing (FDM) systems, and code division multiple access systems (CDMA).MATLAB based teaching tools in signal processing and communication systems courses are becoming an important part of laboratory teaching materials in many universities, because the teaching of these courses might be very challenging if the presentation of abstract mathematical concepts is not supported ...
