#86822 - this is what i am pondering Responding to: ???'s previous message |
I am wondering with the use of a 8052 can i use the telephone to make not realy telephone call but an electrical connection. I know that the phone only handls a analog signal of 400Hz to 3Khz. But could i hypotheticaly use that to my advantage as a carrier wave. modulated by the data which i choose to send. I would think that all that is required is an circuit on the other end to recieve the modulated carrier wave and decode it. |
