5. An FSM can be considered to be a TM1) Of finite tape length, rewinding capability and unidirectional tape movement2) Of finite tape length, without rewinding capability and unidirectional tapemovement3) Of finite tape length, without rewinding capability and bidirectional tapemovement4) Of finite tape length, rewinding capability and bidirectional tape movement6. The functional difference between SR flip-flop and JK flip-flop is that1) JK flip-flop is faster than SR flip-flop2) JK flip-flop has a feed back path3) JK flip-flop accepts both inputs4) JK flip-flop does not require external clock7. The black box in the following figure consists of a minimum complexity circuit thatuses only AND, OR and NOT gates. The function   1,, zyxf whenever x, y aredifferent and 0 otherwise. In addition the 3 inputs x, y, z are never all the same value.Which of the following equation lead to the correct design for the minimumcomplexity circuit?1) yxyx 2) zyx 3) zyxzyx 4) zzyxy 
