DTMF
DTMF is an in-band signaling method using dual sinusoidal signals for any given code. Originally
developed for telephony systems, it has proved a very versatile tool in many other areas.
In two-way radio systems, DTMF is most commonly used for automation systems and remote
control. A common example would be in amateur radio repeaters where some repeaters are
activated by sending out a DTMF sequence (usually a simple single-digit sequence).
