Poszukuję osoby, która mogłaby napisać albo poprawić dostępny skrypt MATLAB pozwalający na wydobycie i analizę sygnału z nagrania oraz porównanie go z danymi referencyjnymi. Opisy i przykłady są dostępne pod linkami: [login to view URL] [login to view URL] [login to view URL] Chodzi mi dokładnie o skrypt/rozwiąznie, który pozwoli na ekstrakcję z nagrania (plik dźwiękowy wav) zakłócenia o częstotliwości około 50 Hz (przydźwięku sieciowego) w postaci jak najdokładniejszego przebiegu czasowo-częstotliwościowego tego konkretnego sygnału. W dalszej kolejności dane te będą porównywane z danymi referencyjnymi pozyskanymi od operatora sieci elektroenergetycznej w postaci odchyłków częstotliwości prądu. Wartości te mierzone są co 1 sekundę z dokładnością do 4 miejsc po przecinku (plik csv z danymi). Wahanie nie przekraczają 1 Hz. Istotne jest uzyskanie możliwości porównania obu sygnałów i wskazania obszaru gdzie sygnały te są zgodne.
