Virtual Laboratory a Key for Teaching Principles of Digital Signal Processing

Abstract

The digital signal processing is a part of data handling so important in today's metrology. Teaching of digital signal processing is carried not only at the electrical and electronic-engineering departments as the most traditional interested in this subject but also others not only technical universities are carried lectures and tutorials. The authors are suggesting how to propose understanding the bases of digital signal processing. The virtual harmonic analyzer, which operates on simulated and real data, is a base. The presented virtual analyzer is a tool for analyzing of quality of electrical power from the point of view of harmonic constants. The proposal delivered here, tells not only how to tackle digital signal processing, but is a tool to identify problems while developing harmonic analyzers
