Applied Geophysics – Analysis and examples Wavelength filtering We have just applied two filters to our data: 1. Regional trend removal: high-pass filter 2. Noise filter: low-pass filter i.e. we have band-passed our data to isolate/enhance gravity anomalies with the wavelength of interest Î Band-pass filter Applied Geophysics – Analysis and examples
