ABSTRACT:
The false-positive detection prevention circuit inputs a multiplexed signal-sliced binary determination value, has an identification code detection circuit for detecting the identification code of the binary determination value and evaluating the identification code, carries out error determination for the identification code evaluation, and outputs a signal that does not correspond to the signal as an error signal. The identification code evaluation carried out by the identification code detection circuit makes reference to the width of the pulse of the binary determination value related to the identification code.
