Abstract

PURPOSE: To carry out the checking for the discontinuation, erasion and others for the pulse by reading out the data with which the synchronous pulse is generated from the memories arranged in a matrix formation plus the data for checking.
CONSTITUTION: Periodic pulses P1∼P5 featuring the waveforms corresponding to the contents written into lines B1∼B5 of ROM are obtained from registers R1∼R5. The output of register RK2 is led to monostable multivibrator RM, and 1 is delivered to output ER1 when no pulse RK2 is transmitted. At the same time, the output of registers R0∼R5plus RK1 and RK2 are led to parity check circuit PC to carry out the parity check.
