Actually, 9 clicks. Of course, It's not just a question of amplifying it - you also need to distinguish this click from any other sound on the line.
That's the hard part! Of course again, But designing a system to preventing of entering other sounds not very hard DTMF is specifically designed to be easily distinguished from normal speech on a telephone line. Yes,Of cource,and this is a challenge that reza must solve it Trouble is, the telephone system gives you no guarantee as to how these pulses will appear at the B-Party's set - if they appear at all!. This project has been done here by my friend, Ali Haj Noroozi In Natinal university of iran Master:Professor Savoji But reza,I say the same as Andy: try to change your project to DTMF instead of Pulse Best Regards Mehdi |
