METHOD OF LOWERING THE IMAGE NOISE IN TELEVISION RECEIVERS

摘要

the invention refers to a method of noise reduction on the image in television receivers.the method according to the invention, provides analysis of high-frequency components in the video signal.the separation of the useful signal from a noise threshold adjustable amplitude and generating a voltage command for enhancement of the tape within the limits for reproduction righthe jumps of signal, in the case of high frequency components in the video.
