A linear feedtack shift register (LFSR) was discussed in class that had three D-flig-flop5, Q2,Q1,Q0. connected in cascade in the order. Q2Q1Q0 and was described by the following feedback excitation equations that provide the D-inputs to the fip flops fwhere denotes the XOR operation\}, D2=Q2oext=Q1Q0D1=Q1oext=Q2D0=Q0orst=Q1 Suppose this LFSR is modifed such that it is now described by the following excitation equations in which the D2 equation is changed. D2=Q2pest=Q2(Q1Q0)D1=Q1uese=Q2D0=Q0inst=Q1 If the modified LFSR is inikialized to the state, Q2Q1Q0=110, that is, the decinal number 6 , then by iterating the above modified exciation equations, show that a repesting, Iengthi. 4 , decimal sequence will be senerated, whose first and last digits within one period are: [6,+,+,3] (6,+,+,5) [6,+,+,7) (6.4,,1]
