Abstract

PURPOSE:To enable the detection of failure in hardware, by sequentially comparing the data at two time point data corresponding to a given period and the next one and producing alarm if there is any disagreement. CONSTITUTION:The output data from a digital signal generator 1 is stored in a register 3 for a certain time. Further, a data is picked up from the register 3 according to the timing pulse from a timing circuit 2, it is compared with the output data at a comparator 4 with a delay of one or a half period from the digital signal generator 1, and the agreement of the both is detected, and if disagreement is found, alarm is produced.
