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.
