ELIMINATION OF WHITE NOISE FROM VIDEO SIGNALS OF TELEVISION TRANSMISSION BY USING DIGITAL RECURSIVE ESTIMATION

Abstract

During the transmission of television signals, because of several sources of electromagnetic noises, video signals are corrupted with white gaussian noise. Generally, the noise is easily observable during the terrestrial transmission of video signals with less then 50 dB IF levels. With the method we have discussed in this paper white noise is eliminated by using recursive estimation of video signals from its past values.
