Consider the degree-4 LFSR given by P(x) = x + x + 1. What is the one period of key stream if the sequence has seed (50 5 5 53 ) = (1111)? (50 51 5 53 54 55) = (111101) (50 51 52 53 54 55) = (111110) (50 51 52 53 54 55) = (111100) (50 51 52 53 54 55) = (111111) Consider the degree-4 LFSR given by P(x) = x + x + 1.
