Apparatus for removing additive disturbance from data channel and method therefor
 An apparatus for detecting and removing an additive disturbance from a signal in a data transmission channel, and an method therefor. The apparatus includes: a disturbance detector which detects whether a disturbance exists in an input signal; a canceling signal generating portion which, when a disturbance is detected by the disturbance detector, generates a canceling signal beginning at the same time as the disturbance, based on a predetermined period of the input signal; and a disturbance remover which subtracts the canceling signal from the input signal to remove the disturbance. Therefore, the canceling signal is generated based on both the output and input signals, thereby precisely removing the disturbance.
