requirements :!:12V, +5V. 3U unsupported card. Parent
equipment EP1M/550. DD 1982.
Drop Shadow Generator. Generates a key signal, from a text
input that is widened downwards to the right. It is used
with the UN14/138 One Line Delay and SE3/511 Split Screen
Switch, to provide insertion of anti-aliased text, with
:!:12V. CH12/64J. DD 1983.
provides C.R.T. unblanking and astigmatism and focus
modulation. X-Axis output, 20 mA peak-to-peak, push-pull.
Other outputs 3 V peak-to-peak max. Power requirements

Subtitle Display Timing Generator. To correct an inherent
fault in the D.M. England Ltd., 'Miracle' subtitle display
and preparation unit, whereby synchronism between a still-
frame l/P video signal and displayed subtitle characters is
lost. This is accomplished by regenerating the corrupted
timing signals produced by the original circuit. Power
requirements 5 V, 500 mA. PCB: 120 mm x 220 mm. DD(7)
Sync Pulse Generator. This unit is part of the send
terminal EP8/4, 6-channel PCM Sound multiplex equipment.
It generates a pseudo-line sync pulse to be added to the
2048kbit/s signal. It is intended to be used when the
equipment is operated on analogue bearer circuits.
CH1.64J. DD 1977.
Timecode Cue Pulse Generator. Compares two 20 bit parallel
words and generates a pulse when the two are equivalent.
Used to compare a running timecode with a fixed time from
thumbwheels to generate a cue pulse. Power requirements
