Abstract
The level of a received data bit is detected at multiple instants which are determined by a clock signal having a frequency higher than that of the data bits to be received. Discrimination of the received data is carried out by considering the bit pattern of the preceding and succeeding bits with respect to the received data, on the basis of the count number of the multiple instants at which the detected levels of the received data bit fall within a specified condition. The reference level for the level detection at the multiple instants, the gate time for allowing the counting of the multiple instants and/or the threshold count number for the discrimination are altered to surely discriminate the levels of the received data bits.
