DEFINITION

Classification: 348/627

Including processing to prevent the addition of noise (e.g., coring enhancement signal, noise responsive peaking control):

(under subclass 625) Subject matter including a specific circuitry to prevent the edge sharpener from adding noise to the original signal.

(1) Note. The noise reduction found in this subclass differs from the noise reduction found in subclass 606 in that the noise reduction in this subclass reduces the noise of a signal added to the original signal while subclass 606 systems reduce noise in the original itself.
