Full Title

Full titles differ between systems:

IPC:

Manipulation of pulses not covered by one of the other main groups of this subclass > Discriminating pulses > Suppression or limitation of noise or interference

CPC:

Manipulating of pulses not covered by one of the other main groups of this subclass (circuits with regenerative action H03K3/00, H03K4/00; by the use of non-linear magnetic or dielectric devices H03K3/45) > Discriminating pulses (measuring characteristics of individual pulses G01R29/02; separation of synchronising signals in television systems H04N5/08) > Suppression or limitation of noise or interference (specially adapted for transmission systems H04B15/00, H04L25/08)

IPC and CPC are identically structured here. All 1 subcodes exist in both systems.

1 shared codes have differing titles between IPC and CPC.

IPC defines codes here since 1995.
