DTMF - Dual Tone Multi-Frequency Open Source Project complete details for free. “DTMF is a signalling system for identifying the keys or better say the number dialled on a pushbutton or DTMF keypad”. In telecommunication, a caller needs to dial the number of the person to which he/she wants to talk. The earlier versions of telephones used to have rotary type dials which are now obsolete. Almost all the landline and mobile phone handsets now use pushbutton keypads. Before DTMF was created, telephone networks used a system called “Decadic”. This system was used extensively in telephone networks to dial numbers, it was a very useful system but limited to the local exchange connections requiring an operator to connect long-distance calls. In the late years of 1950, DTMF was being developed for the purpose of allowing tone signals to dial long-distance numbers, which could be potentially be dialled not only via standard wire networks but also via radio links. The version of DTMF used for telephone tone dialling is known by the trademarked term “Touch-Tone”. ------------------------------------------------------------------------------------------------------------------------- Social Media: ------------------------------------------------------------------------------------------------------------------------- Facebook Page: https://web.facebook.com/innovertz Instagram Page: https://www.instagram.com/innovertz/ Twitter: https://twitter.com/asifayub836 Gmail for any help: [email protected] GitHub Link: https://github.com/MASIFAYUB/Open-Source-Projects ------------------------------------------------------------------------------------------------------------------------- Background Music: ------------------------------------------------------------------------------------------------------------------------- Music: Cinematic Piano - AShamaluevMusic.
