Abstract: A data slicing circuit that receives a demodulated signal including a known data pattern followed by unknown data generates at least two different threshold potentials intermediate between the peak and bottom levels of the demodulated signal. Different comparators compare the demodulated signal with the different threshold potentials to generate at least two different binarized signals. During reception of the known data pattern, a signal processing circuit compares the binarized signals with the known data pattern, preferably oversampling the binarized signals, and selects the binarized signal that best matches the known data. The selected binarized signal is then used to receive the unknown data.

Abstract: A regenerated data signal generation circuit includes a receiving circuit, first and second binarization circuits and a signal preparation circuit. The receiving circuit receives a modulated signal and demodulates the modulated signal. The first binarization circuit receives the demodulated signal and binarizes the demodulated signal while compensates for offset deviation of the demodulated signal by a first method as to output a first binarization signal. The second binarization circuit receives the demodulated signal and binarizes the demodulated signal while compensates for offset deviation of the demodulated signal by a second method that is different from the first method so as to output a second binarization signal. The signal preparation receives the first and second binaraization signals and selectively outputs a regenerated data signal prepared from one of the binarization signals.
