IPC: H04L25/02
Filed: 2000-12-07
Abstract: PROBLEM TO BE SOLVED: To provide a signal detecter circuit which does not cause detection error even if remarkably large noise is superimposed on the signal during transmission of the signal. SOLUTION: A signal which is balance-transmitted 4 from a signal input terminal 1 is amplified in a received signal amplifier 12. Noise superimposed during balanced transmission 4 is attenuated by the amount of a common-mode rejection ratio. Both addition signals are rectified as reception signals and are inputted to a received signal detection amplifier 36. Noise superimposed during the balanced transmission 4 is amplified by a superimposed noise amplifier 18, DC potentials which are set by superimposed DC voltage setting resistors 33 and 34 are superimposed on the noise and are inputted to the received signal detecter amplifier 36 as a detection threshold. Since the detection threshold changes in accordance with the noise quantity superimposed during balanced transmission 4, detection error due to the noise during balanced transmission 4 is not caused.
