The autocorrelation of a linearly swept frequency-modulated sinuusoidal signal used in Vibroseis. It is zero-phase, and symmetrical about time t = 0 ms. Requires f_upper and f_lower, and a duration, which we can interpret from points.
The Ormsby wavelet requires four frequencies: f1 = low-cut frequency f2 = low-pass frequency f3 = high-pass frequency f4 = hi-cut frequency
Together, the frequencies define a trapezoid shape in the spectrum. The Ormsby wavelet has several sidelobes, unlike Ricker wavelets which only have two, one either side.
Also known as the “mexican hat wavelet”, models the function:
Also known as the “mexican hat wavelet”, models the function:
A = (1-2 pi^2 f^2 t^2) e^{-pi^2 f^2 t^2}
The amplitude ‘’A’’ of the [[Ricker wavelet]] with peak frequency ‘’f’’ at time ‘’t’’ is computed like so:
