Abstract
PURPOSE:To obtain a sure bit discriminating circuit which is not influenced by fluctuation of the bit length, by sampling one bit at plural points and by using the sampling value in the center of sampling results to perform majority discrimination. CONSTITUTION:A bit serial signal passes through a signal input circuit 2, and one is inputted to a data inpt terminal D of the first shift register (SR1) 12, and the other is inputted to a sampling pulse generating circuit 11. The sampling pulse generating circuit 11 generates plural sampling pulses during a one-bit period to read data, which is supplied to the data input terminal D of the SR112, into the SR112 in a high speed. The SR112 has output terminals Q1-Q9, and output terminals Q3-Q7 out of them are connected to a majority circuit 13, and the sampling value in the center of the bit is discriminated by majority and is read into the second shift register 4 as the output of the majority circuit 13 by the output obtained by dividing the output of the sampling circuit 10.
