Hello,
I am doing a project on automatic muting tv when phone rings and display the incoming call in lcd. The line voltage condition is 50.1V without ringing and 53V to 55V when receive ring signal. The frequency for the line is approximately 20Hz. Anyone can give me any relevant information or circuit diagram which i can apply in Malaysia for the above condition? Urgent!!!
