Consider the combining function given in the following table, that is used to combine the outputs of four maximum-length LFSR sequences: F(X, X2, X3, X4) = X XX XX3 X X3 X4 XXX3X4 a. (5 pts) The lengths of LFSRS are 60, 95, and 97, and 75 respectively. Compute the linear complexity and the period of the output sequence. b. (15 pts) Analyze the function F in terms of three criteria: Nonlinearity degree Balance Correlation Is this a good combining function? Explain your answer.
