ABSTRACT:
Apparatus and method for chroma noise reduction in a quadrature modulated color television signal path carries out the steps of detecting a chroma signal noise component in the path; detecting predetermined signal characteristics in the path; generating a control signal as a function of the detected signal characteristics wherein the signal characteristics include at least one of: luminance component amplitude, luminance component level transition, and a combination of simultaneously occurring conditions in luminance and chrominance signal components in the path; applying the control signal to separate chroma signal component noise from the predetermined signal characteristics; and subtracting the separated chroma noise in time coincidence with the color television signal in the path, whereby chroma noise is reduced from the signal path without bandwidth reduction.
