| [BBBB]MNI[DM], where [ ] means optional when writing emission specs. [BBBB] = Necessary Bandwidth Uses a letter and three numbers. The letter goes where the decimal point should be placed, and denotes a magnitude: H Hz K kHz M MHz G GHz Some common bandwidths are: 400 Hz "400H" 2.4 kHz "2K40" 12.5 kHz "12K5" 6 MHz "6M00" ___________________________________________ M = Modulation Type N None A AM (Amplitude Modulation), double sideband, full carrier H AM, single sideband, full carrier R AM, single sideband, reduced or controlled carrier J AM, single sideband, suppressed carrier B AM, independent sidebands C AM, vestigial sideband (commonly analog TV) F Angle-modulated, straight FM G Angle-modulated, phase modulation (common; sounds like FM) D Carrier is amplitude and angle modulated P Pulse, no modulation K Pulse, amplitude modulation (PAM, PSM) L Pulse, width modulation (PWM) M Pulse, phase or position modulation (PPM) Q Pulse, carrier also angle-modulated during pulse W Pulse, two or more modes used X All cases not covered above ___________________________________________ N = Nature of modulating signal 0 None 1 Digital, on-off or quantized, no modulation 2 Digital, with modulation 3 Single analog channel 7 Two or more digital channels 8 Two or more analog channels 9 Composite, one or more digital channel, one or more analog X All cases not covered above ___________________________________________ I = Information type N None A Aural telegraphy, for people (Morse code) B Telegraphy for machine copy (RTTY, fast Morse) C Analog fax D Data, telemetry, telecommand E Telephony, voice, sound broadcasting F Video, television W Combinations of the above X All cases not covered above ___________________________________________ [DM] = additional details, not used by FCC, optional elsewhere D = Detail RTTY/modems: A Two condition code, differing numbers or durations (Morse) B Two condition code, same number and duration, no error check C Two condition code, same num & dur, error check D Four condition code, 1 or more bits per condition E Multi condition code, 1 or more bits per condition F Multi condition code, conditions may combine Audio: G Broadcast quality (mono) H Broadcast quality (stereo/multichannel) J Commercial quality K Commercial quality, analog freq inversion or band scrambling L Commercial quality, FM pilot tone (i.e. Lincomprex) Video: M Monochrome N Color W Combination X All cases not covered above ___________________________________________ M = Multiplex type N None C Code division F Frequency division T Time division W Combination of above X All other types ___________________________________________ |
