Abstract
A fixed filter determines a lower portion of the amplitude characteristic of a chrominance signal sideband correction filter. A variable filter determines the upper portion of the amplitude characteristic. A control signal tunes the variable filter for providing a symmetrical response for video signals having balanced color sidebands and tunes the variable filter for providing an asymmetrical response for video signals having unbalanced sidebands.
