Abstract
A repeated information detection system stores incoming information in a RAM store which may have been converted from analog form via a conditioning amplifier and an analog-to-digital converter. On read out, selected information is assigned brightness levels by means of a look-up table, before conversion into analog form in an digital-to-analog converter and then to a display via an amplifier in which synchronizing signals are added. The information read out is varied by controlling the read addressing, the operator being able to select the number of selected points per line and the offset for example, to allow repeated data patterns to be manipulated and detected using visual correlation.
