The Institute was founded in 1960 as the LAS Institute of Electronics and Computer Technique. In 1992 the Institute was reorganized into state non-profit organization-LAS Institute of Electronics and Computer Science. Along with the research in the area of digital signals and data processing, organizational activities have been undertaken connected with the integration into the system of higher education of the Republic of Latvia; as a result in the end of 1996 the Institute joined the University of Latvia. By developing the international co-operation with the Westminster University (Great Britain), in early 1996 an international laboratory 'International Digital Alias Free-Signal Processing Laboratory' (headed by I. Bilinskis, Full mem. LAS) was established and has started active research.

Main Areas of Research and Results

• Digital signal processing.

  The theoretical background for flexibly optimizable digital signal processing has been worked out, and research has begun on evolving such methods and devices which could provide efficient digital signal processing in the microwave frequency band. The obtained results permitted to enlarge the frequency range within the limits of which digital signal processing can be applied. These results provided the possibility together with Westminster University to develop a wide application digital signal processing system 'DASP-Lab System' for GHz range (I. Bilinskis, Full mem. LAS; A. Mikelsons, Cor. mem. LAS; J. Artjuhs, I. Mednieks, V. Bespalko, and V. Vedins). In the field of stochastic discrete stroboscopy conversion methods of noisy signals have been developed for increasing the sensitivity of video-locators in a magnetically contaminated environment (K. Krumins and A. Lorencs). Research on identification parameters and dynamic of functioning of mixed signal systems with non-linear and stochastic properties has been carried out (V. Zagurskis).

• Data processing and transmission systems.

  Functional models of discrete control systems have been developed suitable for using programmable logical integrated circuits as a locally perspective element basis for synthesis of these systems (V. Capenko). Theoretical research in the functional modelling of process-interaction in distributed multimedia systems has been carried out (A. Petrenko and J. Timohovica). Technique for real time system analysis, modelling, and designing has been worked out (A. Baums).

  Mathematical models have been developed for studying the functioning and control processes of distributed data processing and transmission systems as well as systems for solving practical tasks concerning data registration, processing, and transmission. Results of the present research have been used for the optimization of the management of the academic computer network in Latvia (M. Broitmans and J. Kikuts) and solving the control problems of domestic power system (E. Beiners).
