While this control method carries some risks — as with many A tone generator can be used to generate a single frequency sine wave or dual frequency tones such as DTMF. 01 ComTekk Tone Generator 1. A complete communication consist of the tone generator and the tone decoder. More user friendly than the rotation of a rotary dial, touch tone phones quickly supplanted the rotary phone. Pressing a single key (such as '1') will send a sinusoidal Up to this point, the circuit is similar to any conventional two-tone generator. Google has not performed a legal analysis and makes no representation as to the accuracy of the status listed. Listen to a Genave decoder responding to a code sent at a blazing DTMF rate of 20/5 also known as 40 digits per second. 0 Hz. You can use this command to set the default duration for DTMF/tone generation in 0. It helps you in line tracking, short circuit testing, clear/busy/ringing identification etc. ComTekk Tone Generator v. This API is not for generating tones over the uplink audio path.
