The breaking waves dashed high On a stern and rock-bound coast.

—Felicia Dorothea Hemans (1793-1835)

1. Identify the multiples beyond time 9 that are shown in Figure 11b.

Figure 11.  (a) The reflectivity for the case a = 0.8, b = –0.4, and c = 0.7. (b) The resulting impulsive synthetic trace.

2. Figure H-1 shows a zero-phase wavelet with its amplitude spectrum and a minimum-delay wavelet with its amplitude spectrum. The two amplitude spectra are almost the same. Which wavelet is better for processing and which for interpretation?

Figure H-1.  Two wavelets that have approximately the same amplitude spectrum.
