• H03C 1/02 Details
• H03C 1/08 by means of variable impedance element (H03C1/28 - H03C1/34, H03C1/46 - H03C1/52, H03C1/62 take precedence)
• H03C 1/16 by means of discharge device having at least three electrodes (H03C1/28 - H03C1/34, H03C1/50, H03C1/52, H03C1/62 take precedence)
• H03C 1/28 by means of transit-time tube
• 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 1/50 by converting angle modulation to amplitude modulation (H03C1/28 - H03C1/34, H03C1/46, H03C1/48 take precedence)
• H03C 1/52 Modulators in which carrier or one sideband is wholly or partially suppressed (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)
