Ανάπτυξη νέων δομών φίλτρων στο λογαριθμικό πεδίο με χρήση της κυματικής μεθόδου
Τα φίλτρα λογαριθμικού πεδίου (log-domain filters) είναι μια οικογένεια φίλτρων συνεχούς χρόνου στην οποία γίνεται χρήση της μη-γραμμικής I/V χαρακτηριστικής των ενεργών στοιχείων (BJT τρανζίστορ, MOSFET τρανζίστορ σε ασθενή αναστροφή) για να επιτευχθεί γραμμική συμπεριφορά από είσοδο σε έξοδο. …

A tomographic ocean sound speed profile from a long veritcal acoustic array
An average sound speed profile over a 1000 km section of the northeast Pacific ocean is obtained using Ocean Acoustic Tomography, from data acquired during the 1987 SVLA experiment on a long (900 m) 120 hydrophone vertical acoustic array. In particular, we pulse compress the received signal with a …
