State Table (Moore model)

CE 6) A system with one input x and one output z such that z 1iff x has been 1 for at least three consecutive clock times.*
Moore model the output depends only on the state of the system (not thepresent input)

CE 6) A system with one input x and one output z such that z 1iff x has been 1 for at least three consecutive clock times.*
Moore model the output depends not only on the present state of the machine, but also on the present input
