One way to accomplish that goal is to use least-squares shaping filters (see Chapter 9). In other words, we replace the wavelet on a trace on one line with the wavelet from the corresponding trace on the other line. An alternate name for a shaping filter is match filter, which should not be confused with the better-known matched filter (or correlation filter) that is used, for example, in vibroseis correlation. Figure 14 demonstrates the match filter for the case in which a lower-frequency trace 2 is shaped into a higher-frequency trace 1.
