Patent ID: 7098960

Claim:
A data slicer comprising: an A/D conversion unit for converting an input signal including data which are transmitted in serial, into a digital signal; a slice level data calculation unit for calculating plural pieces of slice level data for binarizing the digital signal, on the basis of the digital signal; a binarization unit for binarizing the digital signal using the plural pieces of slice level data, to be converted into plural binarized signals; an extraction pulse generation unit for generating an extraction pulse to be used for extracting the data from the binarized signals; an extraction unit for extracting the data from the binarized signals in accordance with the extraction pulse, thereby generating plural pieces of serial data; a decoding unit for decoding the plural pieces of serial data, thereby generating plural pieces of decoded data; and a decoded data selection unit for selectively outputting decoded data including no error, from among the plural pieces of decoded data.
