Chapter 7. - DTMF
DTMF (Dual-Tone Multi-Frequency) 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).
