Figures
1. Signal transition (one field) - One head is used per
scan
2. Signal transitions (one field) = More than one head
is used per scan
3. Test arrangement for checking the distortion of the
synchronizing signal due to signal transitions
during playback in 'trick'-mode
Specifies the timebase error of the monochrome as well as of the colour composite video signal reproduced from two head helical-scan domestic video recorders, recording one field on each track.
