A sequence detector is a sequential circuit that outputs 1 when a particular pattern of bits sequentially arrives at its data input. Q. zEach state should have output transitions for all combinations of inputs. Sergio__ Lv 7. 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.
