Signal processing laboratory

   The laboratory was established in 1972 and is engaged in theoretical research and practical development of digital signal processing systems, including the development of specific techniques and applications in analog-to-digital signal conversion. The work of the laboratory during these years is reflected in more than 200 publications, conference presentations, and monographs.

  Presently there are 34 people working in the laboratory, including 2 lead researchers, 12 researchers, 8 assistants, 12 engineers and  technicians. 7 employees have doctoral degrees, 11 employees are doctoral students, and 14 employees have master's degrees. Laboratory administrative manager is T. Laimiņa, lead researcher is M. Greitāns
