Study the Effect of Transmission Cable Resistance on Tv – Satellite Image Quality
Abstract
The noise of satellite broadcasting images was statistically analyzed as afunction of values of resistant put in video signal transmission cable in imagesadopted in the study. This was made by using a new method includesmathematically separating of the two noisy effects (additive and multiplicative) byadopting the mathematical models of noise. We have made an algorithm thatincludes effects separation process and finding the site statistical distribution ofthem for each band in the used images. In this study the contrast and edges pointsof the satellite images were calculated. We can note the increase resistant whichput in video signal transmission cable leads to decrease in contrast and rates ofedge and increase in noise.
