• Analysis of aircraft magnetic interference

  Publication

  • M. Wołoszyn

  - Year 2011

  The magnetometric method is used among other things on mobile platforms (planes, helicopters) in military systems and in geological research. Optically-pumped and SQUID magnetometers are used in magnetic systems on airplanes. To be able to attain the sensitivity of modern magnetometers in flight, it is important that maneuver-related magnetic interference effects be minimized. The mathematical model of an aircraft as a source of...

  Artykuł podejmuje niedoceniany problem wpływu liczby i rozkładu głośników w systemach nagłośnienia, na jakość przekazu głosowego, czyli na zrozumiałość mowy w audytoriach. Superpozycji przesuniętych w czasie szerokopasmowych sygnałów o tym samym kształcie i lekko różnych wielkościach, które docierają do słuchacza z licznych spójnych źródeł, towarzyszy zjawisko interferencji prowadzące do głębokiej modyfikacji odbieranych sygnałów...

• Multifrequency self-optimizing narrowband interference canceller

  Publication

  - Year 2010

  The problem of cancellation of a nonstationary sinusoidal interference, acting at the output of a linear stable plant, is considered. It is assumed that disturbance is a multifrequency narrowband signal, and that system output is contaminated with wideband noise. It is not assumed that the reference signal is available. Two disturbance cancelling schemes are proposed, one for disturbances with unrelated frequency components, and...

  W badaniach geologicznych Ziemi wykorzystuje się m.in. metodę magnetometryczną. Metoda ta polega na pomiarze indukcji magnetycznej na badanym obszarze. Na podstawie rozkładu pola magnetycznego można zlokalizować różnego rodzaje złoża mineralne. Poszukiwania geologiczne wykonywane są na dużych obszarach z wykorzystaniem samolotu. Samolot w swoim otoczeniu zniekształca pole magnetyczne, dlatego też system pomiarowy musi zawierać...

• Multichannel self-optimizing narrowband interference canceller

  Publication

  - SIGNAL PROCESSING - Year 2014

  The problem of cancellation of a nonstationary sinusoidal interference, acting at the output of an unknown multivariable linear stable plant, is considered. No reference signal is assumed to be available. The proposed feedback controller is a nontrivial extension of the SONIC (self-optimizing narrowband interference canceller) algorithm, developed earlier for single-input, single-output plants. The algorithm consists of two loops:...

• Improving the quality of speech in the conditions of noise and interference

  Publication

  - Journal of the Acoustical Society of America - Year 2018

  The aim of the work is to present a method of intelligent modification of the speech signal with speech features expressed in noise, based on the Lombard effect. The recordings utilized sets of words and sentences as well as disturbing signals, i.e., pink noise and the so-called babble speech. Noise signal, calibrated to various levels at the speaker's ears, was played over two loudspeakers located 2 m away from the speaker. In...
