A simulated example of severe ghosting in an analog TV broadcast. In television, a ghost is a replica of the transmitted image, offset in position, that is superimposed on top of the main image.

An attenuator inserted in the antenna lead-in wire may be used if the television receiver displays signs of overload in the RF front end. Strong out-of-band signals may also affect television reception and may require band-pass filters to reduce ...
