PURPOSE:To realize an effective application of the fetched logic signal, by having a display based on the number of clocks counted from the time point of generation of a trigger signal through the discontinuation of working of a storing means. CONSTITUTION:A word recognizer 16, etc. produces a trigger signal in response to the logic signal supplied from a comparator 12. Thus a counter 26 is set in an enable state to start counting the clocks. The counter 26 continues counting for a period during which the storage to a storing means which is performed in response to a manual operation of a keyboard 48 is over and then an AND gate 28 is closed by the inversion of an FF 32. The relation is displayed at a CRT 54 between the input logic signal and the trigger signal which are fetched based on the count value of the counter 26 and the processes carried out via a CPU 20, an ROM 42, an RAM 44, etc. The fetched logic signal is used effectively. |
