H03C 1/62
Modulators in which amplitude of carrier component in output is dependent upon
Official title: 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)
H03C1/62 (Modulators in which amplitude of carrier component in output is dependent upon) appears on 71 US grants and 57 published applications in this corpus.
