H03K 17/80

using non-linear magnetic devices; using non-linear dielectric devices

Introduced: September 1968

Title

Titles differ between systems:

IPC: by the use, as active elements, of non-linear magnetic or dielectric devices

CPC: using non-linear magnetic devices; using non-linear dielectric devices

Full Title

Full titles differ between systems:

IPC:

Electronic switching or gating, i.e. not by contact-making and -breaking > characterised by the use of specified components > by the use, as active elements, of non-linear magnetic or dielectric devices

CPC:

Electronic switching or gating, i.e. not by contact-making and –breaking (gated amplifiers H03F3/72; switching arrangements for exchange systems using static devices H04Q3/52) > characterised by the components used (H03K17/04 - H03K17/30, H03K17/94 take precedence) > using non-linear magnetic devices; using non-linear dielectric devices

IPC and CPC are identically structured here. All 4 subcodes exist in both systems.

1 shared codes have differing titles between IPC and CPC.
