9) The analyser generates spatial warnings but it’s not obvious where the pattern is! – Occasionally the
spatial trace may appear when there is no obvious spatial pattern present in the video stream. The

creating faint, repeating structure. Other candidates for generating unexpected spatial responses are:
landscape in perspective, net curtains and reams of paper. However, it is highly unlikely that any of these
scenes would actually lead to a spatial pattern failure.
