Spreadsheet Filtering by FFT Gaussian-based Convolution [PDF]
arXiv, 2004 Filtering of digital signals is accomplished on an Excel spreadsheet using fast Fourier transform (FFT) convolution in which the kernel is either a Gaussian or a cosine modulated Gaussian. Pedagogical examples of low-pass and band-pass filtering are provided, and the practical value of the spreadsheet is illustrated with some cases involving an ...

Hurricane Excitation of Earth Eigenmodes [PDF]
arXiv, 2005 A non-conventional vertical seismometer, with good low-frequency sensitivity, was used to study earth motions in Macon, Georgia USA during the time of hurricane Charley, August 2004. During its transitions between water and land, the powerful storm showed an interesting history of microseisms and also generated more than half-a-dozen surprisingly ...

Correlation measurements of Atmospheric Pressure variations and Seismicity during Hurricane Dennis [PDF]
arXiv, 2005 During the passage of hurricane Dennis, two functionally different instruments made continuous recordings from their location in Macon, Georgia. These were (i) a non-conventional vertical seismometer, and (ii) a low-level differential pressure sensor. Data were collected for 72 hours, beginning when the eye of the storm was located in the vicinity of ...

Fiber optic accelerometers and seismometers
AIP Conference Proceedings, 1996 This paper presents performance and figures‐of‐merit of fiber optic interferometric accelerometers and seismometers using flexural disk, mandrel, and fluid filled transducers. Flexural disk devices having sensitivities of 50 radians/g and operating bandwidths to 2 kHz have been reported. This sensitivity corresponds to a minimum detectable signal of 20
