Full Title

Full titles differ between systems:

IPC:

Electric signal transmission systems > in which the signal transmitted is magnitude of current or voltage > using variable capacitance

CPC:

Electric signal transmission systems (G08C17/00 takes precedence) > in which the signal transmitted is magnitude of current or voltage (G08C19/36, G08C19/38 take precedence) > using variable capacitance

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