CPC: by deflecting an electron beam in a discharge tube (H03D7/20 takes precedence)

Full Title

Full titles differ between systems:

IPC:

Transference of modulation from one carrier to another, e.g. frequency-changing > by deflecting an electron beam in a discharge tube

CPC:

Transference of modulation from one carrier to another, e.g. frequency-changing (H03D9/00, H03D11/00 take precedence; dielectric amplifiers, magnetic amplifiers, parametric amplifiers used as a frequency-changers H03F) > by deflecting an electron beam in a discharge tube (H03D7/20 takes precedence)

No child classifications to compare. This is a leaf node in both IPC and CPC.
