H03B 19/00 Generation of oscillations by non-regenerative frequency multiplication or division of a signal from a separate source (transference of modulation from one carrier to another H03D7/00)
Introduced: September 1968
Title
Titles differ between systems:
IPC: Generation of oscillations by non-regenerative frequency multiplication or division of a signal from a separate source
CPC: Generation of oscillations by non-regenerative frequency multiplication or division of a signal from a separate source (transference of modulation from one carrier to another H03D7/00)
