ABSTRACT:
The present invention is directed to a servo system for compensation of memory signals. In a preferred embodiment, the memory system is a CCD analog read only memory system. In alternate embodiments, the memory system may include an alterable memory, a bubble memory, and/or other memories. Adaptive servo compensation is provided by storing reference signals and compensating stored information signals with the stored reference signals using a compensation servo arrangement. The servo may be an implicit servo for compensating signal amplitude such as to correct charge transfer errors in a CCD memory.
