Introduced: January 1980
Full Title
Full titles differ between systems:
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
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
