Cisco Unified Border Element Configuration Guide DTMF tones are used during a call to signal to a far-end device; these signals maybe for navigating a menu system, entering data, or for other types of manipulation. They are processed differently from the DTMF tones sent during call setup as part of the call control. TDM interfaces on Cisco devices support DTMF by default. Cisco VoIP dial-peers do not support DTMF relay by default and require DTMF relay capabilities to be enabled.

Computational electromagnetics Finite-difference time-domain (FDTD) is a popular CEM technique. It is easy to understand. It has an exceptionally simple implementation for a full wave solver. It is at least an order of magnitude less work to implement a basic FDTD solver than either an FEM or MoM solver.

- Total Harmonic Distortion (THD) analyzer. Total harmonic distortion (THD) is one of the most common and important specification in the audio measurement, which is used to describe the ability of the device to accurately reproduce an input signal at its output.f the soundcard's input and output are connected directly (R ch: ----), distortion of the soundcard itself can be measured. This is called a loopback test, and is very important to perform an accurate measurement.

DTMF (dual tone multi frequency) With DTMF, each key you press on your phone generates two tones of specific frequencies. So that a voice can't imitate the tones, one tone is generated from a high-frequency group of tones and the other from a low frequency group. Here are the signals you send when you press your Touchtone phone keys:

DTMF Decoder DTMF Decoder can process dial tones generated by touch tone phones and log the corresponding phone number. The tone signal is extracted from the telephone line or radio receivers and forwarded to the computer's soundcard for processing. What this application actually does is identify captured sounds and detect their frequencies in order to associate them with a certain key on the phone's number pad.
