(rik’ ∂r) Ondícula de fase cero, la segunda derivada de la función gaussiana o la tercera derivada de la función de densidad de probabilidad normal. La ondícula de Ricker se utiliza a menudo en modelado y fabricación de sismogramas sintéticos. Véase Figura R-14. Nombrado por Norman H. Ricker (1896–1980), geofísico estadounidense.

Sometimes the period (somewhat erroneously referred to occasionally as the wavelength) is given as 1/f, but since it has mixed frequencies, this is not quite correct, and for some wavelets is not even a good approximation. In fact, the Ricker wavelet has its sidelobe minima at

These minima have the value
