 24 Mar 2006 9:02 a circuit for caller id (2) |
|
|
|
hi Professional designers...
i have to design a circuit for Caller ID.when someone call me trough my Caller ID...i must design a circuit than can detect phone number of caller and show it in secret number.for example when Mr.X whit this number :'647587383' call me, my circuit must show it on my Caller ID whit '2' or something else.
but i am a beginner and u r Pro. so i ask u to help me...Please Please Please.
i myself cannot design it.
the circuit can be whit ICs or Microcontrollers. giude me .
Added after 18 minutes:
More explanation about what we want...
i think the circuit must have a FF and a Comparator :when somebody call me,first his\her number compares whit the number that i put in FF and if thay were equal then the caller ID shows it in a secret number that we put in another FF.if they were not equal then the number of caller is shown on CID. so we want a circuit that can detect and decode certain number(numbers that we put in FF),and show it on CID whit (e.g) '1'.
23434655665------shows it-----> 1
87596709587------shows it-----> 2
89745346578------shows it-----> 3
plz help me.
(my english is weak.excuse me)
