A UHFVHFFM antenna consisting of two elongated octagonal elements formed individually from \xbc\u2033 O. When the image signal processor executes an automatic chroma gain control, the image signal processor adjusts a variable rate of ACC gain according to a size of an input color signal to reduce a time for processing the ACC. At least one of the first and second substrate has a three dimensional surface topography covering at least a portion of one of its major surfaces or is distortion sensitive.
