WebDTMF Tones Overview. Dual Tone Multi Frequency (DTMF), is a form of signalling used by phone systems to transmit the digits 0-9 and the * and # characters. Typically a caller presses these buttons on their telephone keypad and the phone then generates a tone made up of two frequencies played simultaneously (hence Dual Tone). WebDual Tone Multi-Frequency (DTMF) is a signaling method used in telephone networks for call set-up, call forwarding control and group calls. This project's purpose is to implement a DTMF receiver that is able to decode a sequence of digits encoded through a …
