IRIG Carrier Frequencies

Each IRIG code specifies a carrier frequency that is modulated to encode date
and time, as well as control bits to time-stamp events. Initially, IRIG applications
were primarily military and government associated. Today, IRIG is commonly
used to synchronize voice loggers, recall recorders, and sequential event loggers
found in emergency dispatch centers and power utilities.
