MEDEL, J. J.; GUEVARA LOPEZ, Pedro  e  FLORES RUEDA, Alberto. Characterization of Real Time Digital Filters to Digital Computers. Comp. y Sist. [online]. 2004, vol.7, n.3, pp.190-209. ISSN 2007-9737.

Digital Filters that interact with dynamic process, produce high quality responses with synchrony and time constraints in critical form. This kind of filters have been known as RTDF (Real-time Digital Filters). This paper explain the next topics: a) Art of state about Filters theory, Real-time theory and Real-time Digital Filter theory. b) Development of theoretical concepts to describe local and global properties of RTDF. c) Implementation of RTDF like as parameter estimator of a D. C. motor. Including an exhaustive analysis of concurrent tasks, precedence constraints and timing constraints in a PC.

Palavras-chave : Digital filter; synchrony; Real-time; tasks; convergence.
