Sobre IBD

Według Farge’a (1992) wyraźnie widać, że tradycyjna analiza Fouriera nie sprawdza się w badaniach zjawisk charakteryzujących się sygnałami niestacjonarnymi lub nawet takich, w których sygnał ulega gwałtownym zmianom częstotliwości. Ta niedoskonałość wymaga zastosowania techniki znanej jako prosta transformacja falkowa (TSO), która posiada ruchome okna w czasie lub przestrzeni, które rozszerzają się lub kompresują, aby uchwycić odpowiednio sygnały o niskiej i wysokiej częstotliwości. Niniejsza książka pokazuje, w kontekście historycznym, potrzebę stosowania TSO jako ważnego narzędzia (techniki) w badaniu zjawisk niestacjonarnych.

    Laut Farge (1992) ist es eindeutig erwiesen, dass die traditionelle Fourier-Analyse bei der Untersuchung von Phänomenen mit nichtstationären Signalen oder sogar solchen, bei denen das Signal starken Frequenzschwankungen unterliegt, nicht anwendbar ist. Diese Unzulänglichkeit erfordert den Einsatz der als Einfache Wavelet-Transformation (EWT) bekannten Technik, die über zeitlich...

    Selon Farge (1992), il est clairement démontré que l’analyse de Fourier traditionnelle n’est pas viable dans l’étude de phénomènes présentant des signaux non stationnaires ou même ceux dans lesquels le signal subit des variations brusques de fréquence. Cette lacune nécessite l’utilisation d’une technique connue sous le nom de transformée en ondelettes simple (TSO), qui comporte...

    Secondo Farge (1992), è chiaramente dimostrato che l’analisi di Fourier tradizionale non è applicabile allo studio di fenomeni che presentano segnali non stazionari o anche quelli in cui il segnale subisce brusche variazioni di frequenza. Tale carenza richiede l’uso della tecnica nota come Trasformata Semplice in Ondine (TSO), che presenta finestre mobili, nel tempo o nello spa...

    Antonio C. S. dos Santos / Augusto C. B. Barbosa / Clênia R. Alcântara
    According to Farge (1992), it is clear that traditional Fourier analysis is not viable in the investigation of phenomena that have non-stationary signals or even those in which the signal undergoes sudden frequency variations. This deficiency requires the use of a technique known as the Simple Wavelet Transform (SWT), which has moving windows, in time or space, that expand or c...
