ABSTRACT:
A digital signal decoding apparatus includes an equalizing section for equalizing a digital signal and outputting a digital signal having effective values at a plurality of sensing points. An extracting section extracts a plurality of amplitude information with narrower timing than the time interval of the digital signal outputted from the equalizing section. A decoding section decodes the digital signal from the plurality of amplitude information extracted by the extracting section. A control section performs a predetermined operation on the plurality of amplitude information extracted by the extracting section and on the basis of the operation result, controlling the level of a reference value used in decoding by the decoding section.
