A TV Ghost Canceller Using a CCD Transversal Filter

A system study has been conducted on a transversal filter ghost canceller to achieve system optimization, and an LSI CCD transversal filter for use in the ghost canceller was developed. Furthermore, a practical model of the ghost canceller was constructed on a trial basis. The results of field tests made on the test equipment showed that this system could improve TV picture quality by more than one grade in a five grade subjective evaluation and that the ghost canceller would be useful in practical applications.
