Abstract
PURPOSE:To prevent malfunction of a data terminal equipment by comparing an error signal quantity detected by a signal comparator circuit with a standard error signal quantity, and disconnecting a switch provided to an output circuit of a majority decision circuit when the large quantity of error signal exists. CONSTITUTION:A signal comparator circuit 4 detects an error signal a1 to output to an integration circuit 7. The integration circuit 7 integrates an error signal a1 inputted sequentially to generate a voltage V corresponding to the signal quantity of the error signal a1. A comparator 8 compares the voltage V corresponding to the standard quantity of the error signal a1 with the voltage V1 corresponding to the standard quantity of the error signal a1, drives a switch 6 in case of V>V1, to interrupt the output circuit of the majority decision circuit 2-3. Thus, when the error signal is large than the standard in quantity, random noise outputted from the majority decision circuit 2-3 is not supplied to the data terminal equipment 3.
