Hi piclisters,

 I=B4ve been googling around to find some info about dtmf decoding using =
pic
micros and I have found some nice circuits. The thing is that most of the=
m
use impedance transformers from the line to the pic in their hardware
interface. The problem is that here in my country is really hard to find
those. Is there any "easier" or maybe "dirtier" way to make the coupling
between the phone line and the pic, so the microcontroller can make the
dtmf decoding? Any suggestion is welcome....

Regards,
*Carlos*
