PURPOSE:To provide the data receiving equipment whose power consumption is reduced by setting successively the arithmetic accuracy in accordance with the degree of a distortion of a receiving signal. CONSTITUTION:In the data receiving equipment provided with an equalizing means 4 for eliminating a distortion of a receiving signal, this equipment is provided with a distortion deciding means 2 for deciding the degree of a distortion of a receiving signal, and an arithmetic accuracy setting means 3 for setting the arithmetic accuracy of an equalizing operation in the equalizing means 4 in accordance with the degree of the distortion decided by this distortion deciding means 2. When the distortion of the receiving signal is small, it is decided by the distortion deciding means 2, and based thereon, the arithmetic accuracy setting means 3 sets the arithmetic accuracy to a lower level than the case when the distortion is large. As a result, the equalizing means 4 executes the equalizing operation with low accuracy, and the power consumption is reduced. |
