Programming Examples

The programs in this chapter are useful as models for a variety of applications that use the DB library. The line numbers are for reference only; they are not part of the programs. Any of these examples can be compiled (under UNIX) using a command of the form

cc file.c -ldb

where file.c is the name of the file containing the source; see section Using the DB Library, for further information. The sources for these examples are included in the DB Software Package, within the `examples' directory.

• Example 1: An annotation filter.
• Example 2: An MIT-to-AHA format annotation translator.
• Example 3: An annotation printer.
• Example 4: Generating an R-R interval histogram.
• Example 5: A program that prints signal specifications.
• Example 6: A differentiator.
• Example 7: A general-purpose FIR filter.
• Example 8: Creating a new DB record.
• Example 9: A signal averager.
• Example 10: A QRS detector.
