Conditions
B-Y output level
fluctuation.
With reference to burst
300 mVp-p.
Level at which killer
output goes high with
burst signal 300 mVp-p
set to 0 dB.
Level at which killer
output goes high with
burst signal 150 mVp-p
set to 0 dB.
B-Y output remaining
level when killer output
is high.
Color killer output level
when color killer is ON,
IOH = –200
µA.
Color killer output level
when color killer is
OFF, IOL = +200
µA.
B-Y output level ratio of
max./min. subcolor.
B-Y output remaining
subcolor difference
level, Color = min.
APC pull-in frequency
