Note: Further Logisim development is suspended indefinitely. An XOR gate implements an exclusive or from mathematical logic; that is, a true output results if one, and only one, of the inputs to the gate is true.If both inputs are false (0/LOW) or both are true, a false output results. It only depends upon the present input. Combinational Logic circuits. Individual logic gates can be connected together to form a variety of different switching functions and combinational logic circuits. Basic Gates. These circuits operate with binary values. Logic gates play an important role in circuit design and digital systems. Truth Tables. A finite-state machine (FSM) or finite-state automaton (FSA, plural: automata), finite automaton, or simply a state machine, is a mathematical model of computation.It is an abstract machine that can be in exactly one of a finite number of states at any given time.
