Abstract

PURPOSE: To secure the announcement of such fault of the medium sending mechanism in the form of the misreading that the information signal to be read by the specified sampling signal and in accordance with the sampling signal is also read by other sampling signals.
CONSTITUTION: If information logic signal 100 and 101 become slower than sampling signal 110 and 111, shift register lock signal 120 is generated by the product of signal 100 and 110. And first step 20 of shift register 5' tirns to "1". As logic sum signal 100 holds "1" between signal 110 and 111, register 5' is never reset. At the same time, register lock signal 121 is generated by the logic product signal of signal 100 and 111. With this signal, register 5' performs the shifting action, and thus both first-step output signal 20 and the second-step signal become "1". And then AND gate 6' is opened to set misreading detecting FF7' for anouncement.
