Noise Suppressing Apparatus Capable of Preventing Deterioration in High Frequency Signal Characteristic After Noise Suppression and in Balanced Signal Transmitting System

摘要

A noise suppressor has signal detecting device 1 for detecting signals A and B on signal lines, sum signal generating device 21 for summing the detected signals, difference signal generating device 22 for differencing the detected signals, noise canceling device 3 for suppressing or removing noise components in a difference signal generated by the difference signal generating device and signal separating device 4 for separating the signal to those corresponding to the signal lines, according to the difference signal with the noise components suppressed or removed and the sum signal.
