Ideally, we want an impulse of zero width'

1
The seismic wavelet

• Ideally, we want an impulse of zero width.
• Practically, the best we can attain is a narrow
  wavelet with minimum sidelobes.
• Examples of practical wavelets are
• Ricker zero-phase wavelet, which approximates
  that of a dynamite.
• Klauder zero-phase wavelet, which approximates
  that of a Vibroseis.
• Berlage minimum-phase wavelet, which approximates
  that of typical impulsive sources.
