  - Rok 2015

  The work presents an implementation of a modular measurement and control systemthat controls variants of mains supply of 230V electrical equipment. The system allowsto supervise power consumption in the office electronic equipment. The system detectsthe instant of the reduced power consumption by a device and makes possible itsswitch-off in order to reduce energy cost. The current is measured with integratedcurrent/voltage converters....

• Digital structures for high-speed signal processing

  Publikacja

  • M. Czyżak

  - Rok 2013

  The work covers several issues of realization of digital structures for pipelined processing of real and complex signals with the use of binary arithmetic and residue arithmetic. Basic rules of performing operations in residue arithmetic are presented along with selected residue number systems for processing of complex signals and computation of convolution. Subsequently, methods of conversion of numbers from weighted systems to...

• A digital implementation of the PSK transmitter and receiver as multirate algorithms of the digital signal processing

  Publikacja

  • K. Świder
  • M. Papaj

  - Rok 2011

  In this paper designs of the transmitter and the receiver of PSK signals as three-rate algorithms of the digital signal processing are described. Additionally we show the examples of the transmitter and the receiver of the following signals: BPSK, QPSK. We discussed also an influence of the cascade of the shaping filter and the receiving filter on the intersymbol interference in the received complex envelope.W pracy opisano projektowanie...

• Digital Processing of Frequency–Pulse Signal in Measurement System

  Publikacja

  • D. Świsulski
  • E. Pawłowski
  • M. Dorozhovets

  - Rok 2018

  The work presents the issue of the use of multichannel measurement systems of sensors processing input value to impulse signal frequency. The frequency impulse signal obtained from such sensors is often required to be processed at the same time with a voltage signal which is obtained from other sensors used in the same measurement system. In such case, it is usually necessary to sample the output signals from all sensors in the...

• Modelling, thermography and digital processing of energy conversion processes

  Publikacja

  • J. Stąsiek

  - Rok 2005

  W pracy przedstawiono zagadnienia modelowania fizycznego i numerycznego procesów wymiany ciepła i konwersji energii. Do analizy wymiany ciepła w przestrzeni wypełnionej płynem zastosowano termografie krystaliczne i komputerowy system analizy otrzymanych laserowych obrazów. Wykonano również termogramy powierzchni pokrytych także ciekłokrystaliczniei jako przykład przeanalizowano rozkład temperatury na powierzchniach ciał stałych...

• Digital signal processing applied to the modernization of Polish Navy sonars

  Publikacja

  • J. Marszal

  - Polish Maritime Research - Rok 2014

  The article presents the equipment and digital signal processing methods used for modernizing the Polish Navy’s sonars. With the rapid advancement of electronic technologies and digital signal processing methods, electronic systems, including sonars, become obsolete very quickly. In the late 1990s a team of researchers of the Department of Marine Electronics Systems, Faculty of Electronics, Telecommunications and Informatics, Gdansk...
