Abstract
A hybrid circuit includes a resistor inserted serially between a transmission line and an output driver for transmitting a signal; and a reception signal extraction unit for extracting only a reception signal from a signal existing in a transmission path by using a signal obtained from both ends of the resistor. The reception signal extraction unit can be constituted by, for example, two transconductance amplifiers for converting the input voltage into a current and a load resistor in which flows the current of a result of adding the output currents of the two amplifiers.
Claims15
A hybrid circuit for separating, from a transmission signal, a reception signal transmitted from a corresponding party of a telecommunication in a bi-directional signal transmission system, comprising:
- a first resistor inserted serially between a transmission line and an output driver for transmitting a signal;
- and
- a reception signal extraction unit for extracting only a reception signal from a signal existing in the transmission line by using a signal obtained from both ends of the first resistor.
