A signal display circuit includes an analog to digital converter, a recirculating memory, a digital to analog converter, and a CRT display means. The memory and the display means are synchronized so that a bright spot representative of the information contained in one location of the memory is produced on the display means for each shifting of information in the memory. New information replaces existing information in the memory at a rate less than the shifting rate of the memory so that the displayed signal appears to move across the viewing screen at a variable speed and with a constant brightness. When no new information is fed into the memory, the display means will continue to show the position of the signal as represented by the data stored in the memory. |
