Abstract

PURPOSE:To protect bipolar violation by a simple circuit by utilizing the regularity of the bipolar violation. CONSTITUTION:Bipolar violation information (a) is sent to shift register 32 via inverter 31 and shifted successively with clock (b). To gate 35, only outputs 39 and 31 among outputs of register 32 are connected via inverters 33 and 34 and 1/8 counter 36 divides the frequency of clock (b) by eight at any time, so that even if information (a) has disturbance, a correct output can be obtained from terminal (d).
