1REC Filter (Digital Demod)

The 1REC filter is for use with CPM Continuous Phase Modulation signals and is required by some CPM standards such as APCO-25 P2 (HCPM).

This is the equation that generates the filter. The value of L is the first number in the filter name. In this case, the name is 1REC so L = 1.
