METHOD AND SYSTEM FOR RELAYING SIGNALS FROM A MAGNETO-INDUCTIVE SYSTEM THROUGH A VOICE-BAND SYSTEM |
摘要 |
A system and method for relaying signals from a magneto-inductive system, which are normally used to communicate between magneto--inductive units using quasi-static magnetic fields, over a voice-band communication system. The magneto-inductive signals are modulated data signals having a carrier frequency typically between 300Hz and 3 kHz. The voice-band communication system facilitates long distance communication of voice-band signals. By supplying the signals from one magneto-inductive unit to the voice-band communication system through an analog input port, the signals are transmitted through the voice-band communication system. They are output from the system through an analog audio output port to the other magneto-inductive unit.
