Abstract
In a decision feedback equalizer, at least one of weighting devices that has a tap coefficient an absolute value of which is relatively larger than absolute values of tap coefficients of other weighting devices is referred to as a main weighting device, and delay elements are disposed asymmetrically on signal processing paths or updating paths of the tap coefficients of the weighting devices in such a manner that an updating interval of the tap coefficient of the main weighting device is shorter than updating intervals of the tap coefficients of the other weighting devices.
