Abstract
A NULL convention-threshold gate receives a plurality of inputs, each having an asserted state and a NULL state. The threshold gate switches its output to an asserted state when the number of asserted inputs exceeds a threshold number. The threshold gate switches its output to the NULL state only after all inputs have returned to NULL. Signal states may be implemented as distinct current levels.
