DIFF Subgroup
H03C 3/40

using two signal paths the outputs of which have a predetermined phase difference and at least one output being amplitude-modulated

Introduced: September 1968

Full Title

Full titles differ between systems:

IPC:

Angle modulation > by converting amplitude modulation to angle modulation > using two signal paths the outputs of which have a predetermined phase difference and at least one output being amplitude-modulated

CPC:

Angle modulation (H03C5/00, H03C7/00 take precedence) > by converting amplitude modulation to angle modulation > using two signal paths the outputs of which have a predetermined phase difference and at least one output being amplitude-modulated

Of 2 combined children, 0 exist in both systems.

2 codes are CPC-only extensions.
