    In this paper, an educational software tool (CELLPLAN) is presented. This tool is used to illustrate to telecommunications engineering students the different steps typically followed in the planning of cellular radio networks. The software tool described in this paper simulates the procedures and algorithms implemented in professional planning tools in a simplified way. The major difference being that no actual terrain information (Digital Terrain Model) is used in the simulations but rather a “generic” terrain configuration is assumed. The availability of this simulation tool in the classroom gives fifth-year telecommunications engineering students the opportunity to tackle realistic cellular network design cases as if they were in a real engineering office View full abstract»

    This short paper modifies a previously described method for the analysis of the five-element-per-phase model of a three-phase induction machine to include the sixth element, the stator core loss resistance r fe. Numerical examples are provided that illustrate the analysis of the resulting six-element model View full abstract»

  • A simple one-dimensional model for the explanation and analysis of GaAs MESFET behavior

    The explanation of GaAs metal-semiconductor field effect transistor (MESFET) operation often involves the use of simplistic analytical formulae, which serve to obscure the more subtle physics of device action. The authors consider here a simple one-dimensional (1-D) model for GaAs MESFETs, which avoids more confusing numerical modeling schemes, yet still facilitates an analysis of the physical functionality of the device. The model takes into account current saturation due to either velocity saturation or channel pinch-off, the modulation of effective gate length and the series resistance of the regions beyond the gate. The results of the model have been compared to experimental data readily obtained from the literature, and the agreement has been shown to be good View full abstract»

  • Effectiveness of computer-aided learning as a direct replacement for lecturing in degree-level electronics

    The application of computer-aided learning as a direct replacement for, as opposed to an adjunct to, lecturing is still in its infancy in higher education. This paper examines some of the reasons for its slow uptake and then describes a project to develop courseware for a large proportion of the electronic engineering syllabus within several UK higher education institutions. The first modules to be completed cover the area of computer engineering. The authors describe the philosophy and design of this courseware, and then report a series of tests in which the examination performance of students using it was compared with that of control groups taught in traditional lectures. The results clearly suggest that carefully designed courseware can lead to a large reduction in teaching time, with no significant difference in learning. They then describe the development of this courseware into what is believed to be the first degree-level electrical engineering course module to be replaced in its entirety by computer-based self-teaching. They discuss the impact of this development on the course structure, and show how the time gained has been used for additional practical work and tutorial support.

  • Experimental verification of the physics and structure of the bipolar junction transistor

    The authors present an electrical characterization of discrete bipolar junction transistor (BJT) devices, with nonuniform doped emitter and base zones. The measurement of the I-V and C-V characteristics of the emitter-base and the collector-base junctions and the common emitter current gain allows to determine relevant parameters of the device. These are the built-in voltage of both junctions, the impurity gradient profiles, the electrical area of both junctions, the base and the emitter Gummel numbers and the collector doping. The whole experiment can be conducted in a laboratory session of 3-4 hour length and it is specifically addressed to students taking lectures in semiconductor device physics. The results obtained give a deep insight into both the physical structure and the physical processes involved in the transistor behavior View full abstract»

  • The design of linear phase FIR filters using the IDFT

    The paper presents a comprehensive set of equations for specifying the transfer function of linear phase finite-impulse response (LPFIR) filters. A procedure for designing the eight possible LPFIR filters (symmetric and anti-symmetric, even and odd length, type 1 and type 2 filters), using the inverse discrete Fourier transform (IDFT) is described. This technique can be equally applied to the window method and the frequency sampling method View full abstract»

  • A novel representation for two-pole feedback amplifiers

    A novel representation of the response of two-pole feedback amplifiers is discussed which is useful both for pedagogical and design purposes. The presented approach allows the parameters of an open-loop amplifier to be appropriately related to the closed-loop requirements such as bandwidth and settling time View full abstract»

  • Photonics laboratory with emphasis on technical diversity

    Page(s): 194 - 202

    The authors describe a recently developed laboratory course in photonics aimed primarily at seniors in electrical engineering. Each student performs four out of seven possible experiments during the quarter in changing teams. The experiments were designed with the following goals: to expose students to widest possible variety of technologically important topics in optics; to allow students the opportunity to use the widest possible variety of laboratory equipment; to foster a healthy respect for potentially dangerous lasers; to encourage individual thinking and self-reliance; and to provide a significant technical writing experience. The experiments themselves are in fiber-optic communication, optical sensing, laser physics, multiple quantum-well detectors, liquid crystals, acoustooptic modulation and solar cells. The authors describe here the experiments, the specific equipment needed to perform them and the structure of their particular course. They also have produced a detailed laboratory manual that is available to other institutions View full abstract»

  • CASE tool learnability in a software engineering course

    Page(s): 185 - 193
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (84 KB)  

    CASE tool learnability is analyzed within the settings of lab sessions associated with an undergraduate software engineering course. The organization of the lab is presented, together with the impact of CASE tool learnability on software development exercises. CASE tool learnability affects the breadth and depth of students' exercises because of the time limitations of the lab sessions. Experienced functionality, determined by the number of functions that have to be exercised by the students versus those available in the tool, is a key aspect of learnability. Students are considered novice users of tools, and their learning time is considered an external indicator of CASE tool learnability View full abstract»
