You can download them from this site (download possibility is following to the tutorial download).Įverything is now terminated and translated and thus you find these themes and projects in part 1 of the tutorial: Part 2 shows Harmonic Balance Simulations on 51 pages.įor chapter 14 (Narrow Bandpass Filter 10,7 MHz) you will need three additional programs. Part 1 shows simulations in the Time Domain and the Frequency Domain using a huge number of projects (= 230 pages, last added chapter is "development of a 1575 MHz

Several complete exercises are illustrated in this work under the proposed concept of simulate-calculate results with the combined use of these two free software environments Qucs-Octave. In both cases, students understand whether they have or not correctly solved the proposed exercises, and they analyse the always existing discrepancies between results. While Qucs offers a friendly environment, free software, to simulate circuits or systems, Octave, which is based on the GNU concept, allows to carry out complex mathematical calculations. This work presents the combined use of free software for the aforementioned purpose of the second stage of the Stepped Practical Work concept for practical training. Finally, in the third and last stage, students access the laboratory to set up circuits or systems with real components, obtaining different measurements of the real quantities involved and validating the calculation methods and results. Another option of this second stage consisting of using a mathematical calculation tool for the same purpose with the objective to validate the results obtained in the first stage. After this stage, students verify that the previously obtained results can be obtained from a based-on PS-SPICE simulation environment software that allows computing various electrical quantities that can be virtually measured. In the first stage, students solve exercises with the only help of a calculator and writing tools. Under the concept of Stepped Practical Work that was successfully implemented in subjects as Basic Electrical Engineering, Electronics, Automation, Navigation and Communications among others, students have to carry out and pass three stages to accredit their practical credits. de Ingenieros Navales from the Universidad Politécnica de Madrid. Teaching circuits, basic electronics or similar contents play an important role in the training of future engineering graduates, even under the perspective that these are not the most important contents for acquiring their regulated competences, as it occurs in the E.T.S.
