DTMF Decoder 

The DTMF decoder circuit monitors to the audio signal from the radio for “Touch-Tone” telephone 
digits. When the digits are discovered, the circuit decodes them and sends to the microprocessor. Mark 
is the amount of time that a tone is being transmitted and “Space” is the amount of time that the tone is 
not being transmitted. 

 

DTMF Decoder Characteristics 

The DTMF decoder circuit can accept signals as fast as 

20

 milliseconds for both Mark and Space 

timing.  

A DTMF string can be anywhere between 

2

 characters long and 

32

 characters long.  

The decoder circuit requires a gap between character strings of 

600 

milliseconds to decode the previous 

string before it can accept another string of characters to decode.
