Abstract
PURPOSE: To prevent the trouble where storage contents do not agree with the trigger signal, by generating the trigger signal by the agreement signal between the select signal of a condition set switch and the sampling signal.
CONSTITUTION: Input signals I1WIn are subjected to waveform shaping by line receiver D and are sent to sampling circuit S and are sampled. The output of circuit S is sent to memory M and is written at the same period as clock 5. The output of circuit S is sent to the trigger circuit also. The trigger circuit consists of AND gate A3, NOR gate A2, and NAND gate A4, and further, trigger signal TG generated first after the end of reset signal 6 is stored by flip-flop F. Further, the AND circuit constitution for the high, off, or low select signal and the sampling signal is given by AND gate A1, and clock 5 is supplied through gate A so that the trigger signal can be generated even if the off signal is selected. As a result, the trouble where storage contents do not agree with the trigger signal can be prevented.
