Field Effects Pulse Generator used in GE2M/573 to provide
the multiple field pulses needed for the special effects
split screen patterns. CH1/43A. DD 1968. DD Spec 8.334.
Pulse Generator used in GE2M/573 to provide
line pulses needed for the special effects
patterns. CH1/43A. DD 1968. DD Spec 8.333.
Split Screen Effects Pulse Generator for driving a split
sawtooth or parabolic line and field components, rolling
of field, displacement by half a picture in either the
line or field direction, ripple modulation in the line
direction, and a box effect having each side independently
positioned. Can be controlled by PA8/516, PN3/23 with
GEI/541, GE1/542, GEI/543, GE1/544, GE2/568, GE2/569,
GE2/570, GE2/57l, GE2/572, OSl/512, 2 UN9/564, UN9/565.
DD 1968. DD Spec 8.386. EDI 10023SEP69. OBSOLESCENT.
Gate Pulse Generator used in EP1/508 to drive UN1/576.
Generates a pulse from mixed syncs to select lines in the
field suppression period which carry test signals.
DD Spec 8.324. ACO. OBSOLESCENT.
Colour Burst Pulse Generator used in GE6M/509 to provide
the colour burst component of the mu1tiburst waveform.
CH1/12A. Superseded by GE6/511. DD 1968. CANCELLED.
Line Selecting Pulse Generator for gating of ITS and
similar signals. From a mixed syncs input it provides a
10~s pulse on each of 4 lines during the field blanking
interval. Integrated circuit version of GE2/552.
DD 1968. WITHDRAWN.
Sync and Burst Pulse Generator used in place of GE2/519 in
AM18/513B when the input is black level (syncs and burst)
and not mixed
DD 1968. DD Spec 8.322. ACO. BSOLESCENT.
Waveform Timing Pulse Generator identical with GE2/565 but
on half width chassis CH1/43. DD 1968. WITHDRAWN.
Suppression Pulse Generator with a similar function to
GE2/517A but is not a plug-in replacement. Provides an
output of mixed suppression and field suppression at 75~
from an input of mixed syncs. CH1/12A. DD 1968.
Variable Line Selecting Pulse Generator used to provide,
from a composite video input, a line identifying pulse of
lines 6 to 27/319 to 340.
system). Also supplies various trigger pulses for display
purposes. Mains operated. CH1/12A. DD 1968.
