PURPOSE:To make it possible to discriminate data containing by a method wherein a glitch is detected from an input logic signal by a glitch detecting means and the display of the character of the input signal containing the glitch is controlled by a character display control means. CONSTITUTION:The data component and the glitch component among the input logic signals from a probe 10 are stored by respective memory circuits 14, 18 through a block 12 and, when a display order is inputted from a keyboard 30, CPU24 transmits the memory contents of the memory circuits 14, 18 to RAM28 on the basis of the firm wear of ROM26. In addition, a display mode and display region information selected by the keyboard 30 are stored by RAM 28 and a display control circuit 32 repeatedly read the content of the display RAM region of RAM28 to display a logic state by CRT34. |
