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 signals.
