manufacturer:linear description:following the filter section is a decoder employing digital counting techniques to determine the frequencies of the incoming tones and to verify that they correspond to standard dtmf frequencies. a complex averaging algorithm protects against tone simulation by extraneous signals such as voice while providing tolerance to small frequency deviations and variations. this averaging algorithm has been developed to ensure an optimum combination of immunity to talk-off and tolerance to the presence of interfering frequencies (third tones) and noise. when the detector recognizes the presence of two valid tones (this is referred to as the signal condition in some industry specifications) the early steering (est) output will go to an active state. any subsequent loss of signal condition will cause est to assume an inactive state (see steering circuit). |
