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)
