Introduced: January 1990

Full Title

Full titles differ between systems:

IPC:

Modulated-carrier systems > Carrier systems characterised by combinations of two or more of the types covered by groups , , , or > Amplitude- and phase-modulated carrier systems, e.g. quadrature-amplitude modulated carrier systems > Modulator circuits; Transmitter circuits

CPC:

Modulated-carrier systems > Carrier systems characterised by combinations of two or more of the types covered by groups H04L27/02, H04L27/10, H04L27/18 or H04L27/26 > Amplitude- and phase-modulated carrier systems, e.g. quadrature-amplitude modulated carrier systems > Modulator circuits; Transmitter circuits

Of 4 combined children, 0 exist in both systems.

4 codes are CPC-only extensions.
