Bit
DTMF Receiver Notch Filter Center Frequency:
NCF = 32768
0 Hz
The bytes are calculated as follows:
NCF-L = MOD (NCF,256) = NCF & 0x00FF
NCF-H = INT (NCF/256) = NCF >> 8
The echo of the dial tone can activate the double talk detection which means that the
DTMF tone will not be detected. Therefore a notchfilter can be programmed to filter out
the echo of the dialtone, because the frequency of the dialtone is known. The center
frequency and the bandwith of the notch filter can be programmed.
