H03K 19/16

using saturable magnetic devices

Introduced: September 1968

Full Title

Full titles differ between systems:

IPC:

Logic circuits, i.e. having at least two inputs acting on one output; Inverting circuits > using specified components > using saturable magnetic devices

CPC:

Logic circuits, i.e. having at least two inputs acting on one output (circuits for computer systems using fuzzy logic G06N7/02); Inverting circuits > using specified components (, H03K19/003 - H03K19/0175 take precedence) > using saturable magnetic devices

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