ABSTRACT:
A simultaneous bidirectional transmission apparatus for transmitting and receiving differential signals solves a generation of pulse noise problem in the receiving circuit due to the inversion of the output of the transmission circuit. For a pair of input/output devices connected together by transmission lines, each input/output device has a differential transmitting circuit, a differential receiving circuit and six resistors. The output of the transmitting circuit does not affect an input to the receiving circuit, and the receiving circuit receives only the output of the transmitting circuit of the other input/output device. The resistors, a passive element circuit and the output resistance of the transmitting circuit form, in combination, a waveform shaping filter and a matching terminating circuit.
