ghost
In the transmission or recording of raster-scanned analog television signals, an artifact manifested as a weak, ghost-like secondary image, offset (in the direction of the scan) with respect to the position of the primary image. Note: Ghosting is probably most familiar as a consequence of multipath rf reception of a broadcast television signal. The slight delay in the arrival time of the reflected signal results in the display of a secondary image that follows the primary. In the playback of a tape-recorded program, ghosting may also be introduced by print-through in the magnetic tape medium.
