Abstract
A receiver for receiving a signal transmitted from a transmitter via a transmission line of the present invention includes: a current control section for allowing a current to flow into the current control section from the transmission line or flow from the current control section to the transmission line, wherein the current has an amount which varies according to a logical level of the signal and flows in a same direction irrespective of the logical level of the signal; and a determination section for determining the logical level of the signal based on the amount of current which has flowed from the transmission line into the current control section or based on the amount of current which has flowed out from the current control section to the transmission line.
Claims19
A receiver for receiving a signal transmitted from a transmitter via a transmission line, the receiver comprising:
- a current control section for allowing a current to flow into the current control section from the transmission line or flow from the current control section to the transmission line, wherein the current has an amount which varies according to a logical level of the signal and flows in a same direction irrespective of the logical level of the signal;
- and
- a determination section for determining the logical level of the signal based on the amount of current which has flowed from the transmission line into the current control section or based on the amount of current which has flowed out from the current control section to the transmission line.
A signal transmission system for transmitting a signal via a transmission line, the signal transmission system comprising:
- a current supply section for supplying a current to the transmission line, wherein the current has an amount which varies according to a logical level of the signal and flows in a same direction irrespective of the logical level of the signal;
- a current control section for allowing the current to flow into the current control section from the transmission line or flow from the current control section to the transmission line irrespective of the amount of the current supplied from the current supply section to the transmission line;
- and
- a determination section for determining the logical level of the signal based on the amount of current which has flowed from the transmission line into the current control section or based on the amount of current which has flowed out from the current control section to the transmission line.
A receiver for receiving a signal transmitted from a transmitter using a first transmission line and a second transmission line, wherein:
- a current flows through the first transmission line and the second transmission line, wherein the current has an amount which varies according to a logical level of the signal and flows in a same direction irrespective of the logical level of the signal;
- and
- the receiver comprises:
- a difference current compensation section for compensating for a difference current having an amount which represents a difference between the amount of current flowing through the first transmission line and the amount of current flowing through the second transmission line;
- and
- a determination section for determining the logical level of the signal based on the difference current.
A signal transmission system, comprising a transmitter, a receiver, and a first and second transmission line for connecting the transmitter and the receiver to each other, for transmitting a signal from the transmitter to the receiver using the first transmission line and the second transmission line, wherein:
- the transmitter comprises a current supply section for supplying, to the first transmission line, a current having an amount which varies according to a logical level of the signal;
- the receiver comprises a determination section for determining the logical level of the signal based on a difference current having an amount which represents a difference between the amount of current flowing through the first transmission line and the amount of current flowing through the second transmission line;
- and
- the first transmission line and the second transmission line are formed by folding back a single transmission line.
