Digital processing and reconstruction of complex signals

In real electronic systems, voltage and current signals are not necessarily of a periodical quantity, due to the presence of nonharmonic components or/and possible stochastic variation. This book presents in three parts methods for analyzing and processing and reconstructing complex signals. The first part of this book is dedicated to the problem of measurements of the basic electric quantities in electric utilities, both from the aspect of accuracy of this type of measurements and the possibilities of simple and practical realization. Thesecond part presents a reconstruction of trigonometric polynomials, a specific class of band-limited signals, from a number of integrated values of input signals. The third part deals with the problem of estimating the value of the active power of the ac signal in the presence of subharmonics and interharmonics. The analysis makes use of the most general model of the voltage and currentsignal, i.e. the most complex spectral content that can be expected to appearin practice. INDICE: Introduction.- Digital Processing of Synchronously sampled AC signals in Presence of Interhatmonics and Subharminics.- Reconstruction of Non-uniformly Sampled AC Signals.- New Method for Processing Basic Electric Values onthe Definition Formula in Time Domain- Hardware Realization.
