When the edge filter is enabled, certain data transitions between two levels are run
through a low-pass filter to set rise times, pulse widths, and to prevent ringing.
If the filter is disabled, the edges will not be filtered. The filter should not be
disab
led in broadcast environments.
Edge filtering is not n ecessary in certain environments, such as digital cinema
appl
ications and several types of picture monitors and projectors. In these cases,
disabling the edge fi ltering will result in instantaneous level changes for adjacent
color bars.
NOTE. Software versions of the HD3G7 module prior to V5.5 included a 2K TEST
SIGNAL KEY ASSIGN menu to select pro jector-specifi
c test patterns that had no
edge filtering. With software version V5.5, this functionality has been replaced by
t
he Edge Filter s ubmenu, which can be applied to any test signal.
