- pylops.utils.wavelets.ormsby(t, f=(5.0, 10.0, 45.0, 50.0), taper=None)[source]¶
Ormsby wavelet
Create a Ormsby wavelet given time axis
tand frequency range defined by four frequencies which parametrize a trapezoidal shape in the frequency spectrum.- Parameters:
- t
numpy.ndarray Time axis (positive part including zero sample)
- f
tuple, optional Frequency range
- taper
callable, optional Taper to apply to wavelet (must be a function that takes the size of the window as input
- t
- Returns:
- w
numpy.ndarray Wavelet
- t
numpy.ndarray Symmetric time axis
- wcenter
int Index of center of wavelet
- w
