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 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 CANCELLING 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.
