Abstract
A digital communication system comprising a host and a client, the host calls the client via two transmission lines. The host includes a processor, a first control unit, a second control unit, a high frequency transformer and an interface unit. The digital communication system utilizes the first control unit and the high frequency transformer to modulate outgoing signals. The digital communication system utilizes the second unit and the high frequency transformer to demodulate incoming signals.
Claims16
A digital communication system comprising:
- a host communicated with a client via an interface unit;
- the host comprising a processor, a first control unit, and a high frequency transformer comprising a primary winding and a secondary winding,
- wherein the primary winding comprises a first sub-winding and a second sub-winding;
- the first sub-winding comprises a first terminal and a third terminal;
- the second sub-winding comprises a second terminal and a fourth terminal;
- the first terminal and the second terminal connect to the interface unit;
- the third terminal and the fourth terminal connect to a direct current (DC) power;
- when the host communicates with the client, the processor outputs a first channel signal and a second channel signal to the first control unit, the first control unit and the high frequency transformer modulate the first channel signal and the second channel signal into a first digital signal, and the first digital signal is transmitted to the client via the interface unit.
A digital communication system comprising:
- a host communicated with a client via an interface unit;
- the host comprising a processor, a first control unit, and a high frequency transformer;
- wherein the processor outputs a first channel signal and a second channel signal, the high frequency transformer modulates the first channel signal and the second channel signal into a first digital signal and transmitting the first digital signal to the client via the interface unit, and the high frequency transformer connects to a direct current (DC) power to supply power to the host and to provide a DC carrier voltage for the first digital signal;
- and
- wherein the high frequency transformer comprises a primary winding and a secondary winding, the primary winding comprises a first sub-winding and a second sub-winding;
- the first sub-winding comprises a first terminal and a third terminal;
- the second sub-winding comprises a second terminal and a fourth terminal;
- the first terminal and the second terminal connect to the interface unit;
- the third terminal and the fourth terminal connect to the DC power.
