is there any important point to be considered while interfacing the
DTMF chip to the phone line?
i 'm currently working on a DTMF decoder proj and got stuck at the
interfacing between the telephone line and the DTMF MT8870 and the
interfacing between MT8870 and PIC18F452.
somebody pls suggest me on this.
thanks.
