DTMF Sequence Encoder and Decoder

DTMF Sequence Encoder and Decoder

The DTMF sequence encoder creates dual-tone multi-frequency tone sequences of variable frequency, amplitude, and duration. It’s signal can be used to modulate the RF generator, or it can be output through the AUDIO OUT connector.

The DTMF sequence decoder analyzes dual-tone multi-frequency tone sequences and displays the associated parameters.

Measurement Limits

Lo Tone: 680 - 960 Hz

Hi Tone: 1190 - 1660 Hz

Actual limits are typically slightly wider than this. However, the crossover point between Hi and Lo tone decoding is approximately 1.1 kHz. If incoming tones approach this point, unreliable measurements may be displayed (frequency measurement errors and spurious off times).
