CLASS OF EMISSION
================================================================
FIRST COLUMN
================================================================
CODE TYPE OF MODULATION
================================================================
N Emission of an unmodulated carrier.
Emission in which the main carrier is amplitude modulated.
(Including cases where sub-carriers are angle modulated.)
A Double-sideband.
H Single-sideband, full carrier.
R Single-sideband, reduced or variable level carrier.
J Single-sideband, suppresed carrier.
B Independant Sideband.
C Vestigal sideband.
Emission in which the main carrier is angle-modulated.
F Frequency Modulation.
G Phase modulation.
D Emission in which the main carrier is amplitude and
angle-modulated either simulataneously or in a pre-
established sequence.
Emission of Pulses
P Unmodulated sequence of pulses.
A Sequence of pulses.
K Modulated in amplitude.
L Modulated in width duration
M Modulated in position/phase.
Q In which the carrier is angle-modulated during the
period of the pulse.
V Which is a combination of the foregoing or is produced
by other means.
W Cases not covered above, in which an emission consists
of the main carrier modulated, either simultaneously
or in a pre-established sequence, in a combination of
two or more of the following modes: amplitude, angle,
pulse.
X Cases not otherwise covered.

SECOND COLUMN
================================================================
CODE NATURE OF SIGNAL(S)
================================================================
0 No modulating signal.
1 A single channel containing quantitized or digital
information without the use of a modulating sub-carrier.
2 A single channel containing quantitized or digital
information in with the use of a modulating sub-carrier.
3 A single channel containing analogue information.
7 Two or more channels containing quantitized or digital
information
8 Two or more channels containing analogue information.
9 Composite systems with one or more channels containing
quantitized or digital information, together with one
or more channels containing analogue information.
X Cases not otherwise covered.

FOURTH COLUMN
================================================================
CODE DETAILS OF SIGNAL(s)
================================================================
A Two-condition code with elements of differing numbers
and/or durations.
B Two-condition code with elements of the same number
and duration without error - correction.
C Two-condition code with elements of the same number
and duration with error - correction.
D Four-condition code in which each condition represents
a signal element (of one or more bits).
E Multi-condition code in which each condition represents
a siganl element (of one or more bits).
F Multi-condition code in which each condition or
combination of conditions represents a character.
G Sound of broadcasting quality (monophonic).
H Sound of broadcasting quality (stereophonic or
quadrophonic).
J Sound of commercial quality (excluding categories given
under K and L below).
K Sound of commercial quality with the use of frequency
inversion or band-splitting.

modulated signals to control the level of demodulated
signals.
M Monochrome.
N Colour
W Combination of the above
X Cases not otherwise covered.
