  • H03C 1/32 by deflection of electron beam in discharge tube
  • H03C 1/34 by means of light-sensitive element
  • H03C 1/36 by means of semiconductor device having at least three electrodes (H03C1/34, H03C1/50, H03C1/52, H03C1/62 take precedence)
  • H03C 1/46 Modulators with mechanically-driven or acoustically-driven parts
  • H03C 1/48 by means of Hall-effect devices
  • H03C 1/50 by converting angle modulation to amplitude modulation (H03C1/28 - H03C1/34, H03C1/46, H03C1/48 take precedence)
  • H03C 1/62 Modulators in which amplitude of carrier component in output is dependent upon strength of modulating signal, e.g. no carrier output when no modulating signal is present (H03C1/28 - H03C1/34, H03C1/46, H03C1/48 take precedence)
