Majority or minority circuits, i.e. giving output having the state of the majority or the minority of the inputs

Introduced: January 1980

Full Title

Full titles differ between systems:

IPC:

Logic circuits, i.e. having at least two inputs acting on one output; Inverting circuits > characterised by logic function, e.g. AND, OR, NOR, NOT circuits > Majority or minority circuits, i.e. giving output having the state of the majority or the minority of the inputs

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 > characterised by logic function, e.g. AND, OR, NOR, NOT circuits (H03K19/003 - H03K19/01 take precedence) > Majority or minority circuits, i.e. giving output having the state of the majority or the minority of the inputs

No child classifications to compare. This is a leaf node in both IPC and CPC.
