Kwadraturowy DDS z ułamkowo-opóźniającym filtrem o strukturze flash-Farrow.
PublikacjaW pracy omawiamy nieliniowy algorytm cyfrowego generatora z syntezą bezpośrednią, zwanego krótko DDS od ang. Direct Digital Synthesizer. Proponujemy nowy algorytm kwadraturowego DDS. Pozwala on osiągnąć zarówno wysoki stopień czystości generowanej sinusoidy kwadraturowej, jak i bardzo małe błędy modulacji częstotliwości (FM) przy małej pojemności pamięci ROM, od której zależy pobór mocy zasilania. Ponadto proponujemy nowe podejście...

Limiting distribution of Lempel Ziv'78 redundancy
PublikacjaWe show that the Lempel Ziv'78 redundancy rate tends to a Gaussian distribution for memoryless sources. We accomplish it by extending findings from our 1995 paper [3]. We present a new simplified proof of the Central Limit Theorem for the number of phrases in the LZ'78 algorithm. As in our 1995 paper, here we first analyze the asymptotic behavior of the total path length in a digital search tree (a DST) built from independent sequences....

Continuous wave sonar with hyperbolic frequency modulation keyed by pseudo-random sequence
PublikacjaA CW FM type sounding signal is used in the classical solution of silent sonar. While the signal provides a relatively simple implementation of digital signal processing, and ensures good detection conditions, unfortunately, in the presence of the Doppler effect, distance measurement results tend to be wrong. This is due to the fact that the received signal’s instantaneous frequency value is dependent both on the distance to the...
