DTMF uses a combination of two (one low frequencyand one high frequency) tones to identify the diallednumber or a signal.
Eight such frequencies are assigned to the four rows
and four columns of a typical push-button type dial(keypad).
With DTMF, each key you press on your phone generates
two tones of specific frequencies.
A DTMF keypad (generator or encoder) generates a
sinusoidal tone which is mixture of the row and column
frequencies.
