Abstract

PURPOSE: To permit the size of data or the like to be uderstood with eyes by using the X-axis for time dimension, displaying data quantity converted into analog in the Y-axis direction, and allowing the difference between contents in the memories of two independent systems to be displayed.
CONSTITUTION: Data stored in memories 1 and 2 are added to a switch 5 at each address controlled by an address counter 3, being subtracted in a subtraction circuit 4. The switch 5 is possible to set from outside, and its output is applied to the Y-axis of CRT8 via a DA converter 6. On the other hand, the address signal from the address counter 3 is applied to the X-axis via a DA converter 7. Thus, since the displayed wave-form is analog, the size and the difference between two kind of data can be instinctively and readily seen.
