CDl MISCELLANEOUS CODERS
Insert/Extract Coder, used in EP8M/S04, EP8L/SOS, EP8L/S06
to enable an 8 bit parallel input to be encoded to a 16
element serial PSK output; also enables a 16 element
serial PSK to be decoded to an 8 pit parallel output.
CHl/63. DD 1972. OBSOLESCENT.
CDl Sub Group not available for new designs DD 1977.
Stereophonic Encoder for multiplexing two zero-volume
audio signals in accordance with the Pilot-Tone
Stereophonic Transmission System. CHl/18F. CANCELLED.

or closes 8 input points and pre-sets a shift register
which is emptied by the joint presence of the sub-channel
gated signal from UN23/l0 and the clock signal from
UN17/Sl9 during which time no date is accepted. ISEP card
with 25 way plug, coding positions 3, 9, 11. DD 1968.
DD Spec S.lS7. WITHDRAWN.
PAL Colour Coder comprising CD2/S04 with PN3A/16C equipped
terminating resistors together with a subcarrier phase
shifting network. Superseded by CD2L/S22,A. DD 1969.
