INDUSTRY CANADA/INDUSTRIE CANADA TABLE II 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. ================================================================ THIRD COLUMN ================================================================ CODE TYPE OF INFORMATION ================================================================ N No information transmitted. A Telegraphy - for aural reception. B Telegraphy - for automatic reception. C Facsimile. D Data transmission, telemetry, and telecommand. E Telephony ( including sound broadcasting). F Television (video). W Combination of the above. 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. L Sound of commercial quality with separate frequency- modulated signals to control the level of demodulated signals. M Monochrome. N Colour W Combination of the above X Cases not otherwise covered. ================================================================ FIFTH COLUMN ================================================================ CODE NATURE OF MULTIPLEXING ================================================================ N None. C Code-division. F Frequency-divsion multiplex. T Time-division multiplex. W Combination of frequency-division multiplex and time-division multiplex. X Other types of multiplexing.
