Homework Statement


I want to design a circuit that is able to differentiate an sms signal and also a telephone signal. What I mean is the telephone signal is when someone calls you.

Example , when someone sms you , your circuit will detect the sms signal and LED 1 will light up (use to indicate the signal) or when someone is calling you , your circuit will detect the telephone signal , LED 2 will light up

Homework Equations




The Attempt at a Solution


Can anyone give me some hints on where I can go about?

How would you proceed?

What have you learned about so far in electronics that would help here?

I am not really sure which is why I am asking for some hints here. I am not asking that you help me solve my problem by giving me solution. I am asking for information on where I can begin searching for solution to my problem. for example some key term that might give me some clue to my answer
