Title:Knowledge - base for engineering design of electronic digital filters
Author:Mollova, Gergana StoychevaDate:1994Abstract:A knowledge base, consisting of topological circuit structures and computational procedures is discussed. It is intended for computer-aided design of recursive digital filters. This knowledge base is an inherent part of a program system for engineering use. The data-transfer between the knowledge base unit and the other units of the system ...Library:

Title:C - Realization of a real-to-complex conversion structure for radar signals
Author:Tchamova, Albena PlamenovaDate:1994Abstract:Complex signals are discussed in digital signal processing for several reasons. In some cases the required processing can be made more efficiently using such kind of signal representation, in other cases the envelop, or phase of considered signal are of interest and it is suitable to extract them from complex data. It is a problem, closely ...Library:

Title:Speeding up test generation for combinational digital circuits using transformations
Author:Roussev, Borislav NickolovDate:1994Abstract:The theoretical study of Ibarra and Sahni [1] shows that test generation for combinational circuits is an NP-complete problem. The aim of the paper is to speed up the test generation for combinational circuits.
The present exploration is inspired by the theory of Petri Nets [2]. A number of NP-complete analysis techniques for Place/transition ...Library:

Title:Self-checking implementation of Boolean interpreted Petri nets
Author:Roussev, Borislav NickolovDate:1994Abstract:This paper presents a technique of constructing a self-checking synchronous implementation of a Boolean Interpreted Petri Net. The validated Petri net specification is modeled with a circuit that automatically detects faults visible at Petri net level. The so called direct approach is used in modeling Petri nets by hardware. The faults that ...Library:
