Amplitude-modulated carrier systems, e.g. using on-off keying; Single sideband or vestigial sideband modulation (H04L27/32 takes precedence)

Introduced: September 1968

Title

Titles differ between systems:

IPC: Amplitude-modulated carrier systems, e.g. using on/off keying; Single sideband or vestigial sideband modulation

CPC: Amplitude-modulated carrier systems, e.g. using on-off keying; Single sideband or vestigial sideband modulation (H04L27/32 takes precedence)

Full Title

Full titles differ between systems:

IPC:

Modulated-carrier systems > Amplitude-modulated carrier systems, e.g. using on/off keying; Single sideband or vestigial sideband modulation

CPC:

Modulated-carrier systems > Amplitude-modulated carrier systems, e.g. using on-off keying; Single sideband or vestigial sideband modulation (H04L27/32 takes precedence)

IPC and CPC are identically structured here. All 3 subcodes exist in both systems.
