Description
Adaptive Digital’s DTMF tone analysis software is designed to analyze DTMF tones and report the following statistics:
- Twist: The difference in signal level between the high band frequency and the low band frequency
- Duration: The duration of the tone
- Level: The level of both the low band and high band frequencies.
- SNR: The signal to noise ratio
- Frequency: The frequencies of the low band and high band frequencies
The DTMF tone analysis software works in conjunction with Adaptive Digital’s DTMF detector which, by itself, does not perform this more complete analysis of the DTMF signal.
