This paper describes a basic electronics learning system combining a hypermedia system explaining theoretical concepts with a basic simulator and a virtual laboratory to improve the engineering education process on electronics and the students skills before going to the actual laboratory. To accomplish this objective the system also provides a set of complementary resources, constituting a brid...

This paper contains the motivation for the study of critical surfaces in [2]. In that paper, the only justification given for the definition of this new class of surfaces is the strength of the results. However, when viewed as the topological analogue to index 2 minimal surfaces, critical surfaces become quite natural.

A fault-based multifrequency test generation and fault diagnosis procedure is proposed in this work. The procedure selects a minimal set of test measures and generates the minimal set of frequency tests which guarantee maximum fault coverage and maximal diagnosis of circuit AC hard/soft faults. The procedure is exempli ed for several self-testable linear analog circuits.

The paper presents the results of applying the VISIR (Virtual Instrument Systems in Reality) system at the course of analog electronics for various degrees of the Faculty of Engineering of the University of Deusto (Spain). The efficiency of the VISIR had been monitored during past three years. Students’ feedback was collected and analyzed. The research shows: 1) VISIR system is functional and u...

Methods applicable to teaching microelectronics at the undergraduate and graduate level in conjunction with an industrial fabrication capability are presented. Results of three semesters of teaching microelectronics at the graduate level with emphasis on both digital and analog circuits are summarized. Plans for teaching an undergraduate course utilizing the fabrication of integrated circuits a...

This paper introduces the class of reflected number systems. Members of this class have the adjacency property, i.e. representations for consecutive numbers differ in only one digit and the magnitude of this difference is one. It shows that every number system based on a positional weighting scheme has a reflected analogue. It presents procedures to convert a number system to its reflected anal...
