BDUM

This program reads a *.seg file, adopts the headers and replaces the data with an impulse at a user specified time. It can be used to present an impulse response or to benchmark software and do testing. In the following example, the filter program is illustrated. See Figure 56.
 bdum   infile   time_impulse 
  
EXAMPLE: filter an impulse at 0.1 seconds, headers from c008.seg
bdum c008.seg .1
bfil bdumc008.seg 1 6 40 40 1
