Abstract

PURPOSE:To make easy the adjustment, by simplifying the circuit, through the bit synchronism and code reproduction of bipolar code at the same time with a simple circuit constitution. CONSTITUTION:In the bipolar code reproduction circuit, it is provided with the input terminal 1 inputting the bipolar signal received and amplified with equalization, differentiation circuit 11 differentiating the inputted signal to the terminal 1, and the pulse generation circuit 17 inputting the output of the voltage controlled oscillator 16 generating the clock pulse varied for the frequency, and further, with the sample hold circuit 12 performing sample hold the output of the circuit 11 at the leading of the pulse of the circuit 17. Further, the analog addition and subtraction in common use with integrating circuit 15 which multiplies +a, 0, -a (where; a is a constant) with the output of the circuit 12 at the judgement time point of +1, 0, -1 of the result of the code judgement with the comparators 2, 3 and FF6, 7 for the input signal from the terminal 1, is provided, and the oscillator 16 is controlled so that the output of the circuit 15 zeroes the output of the circuit 11 at the leading of the clock pulse for the output frequency of the circuit 17.
