If x(n) is an imaginary sequence, then the z-transform of the real part of the sequence is:
A. 1/2[X(z)+X*(z*)]
B. 1/2[X(z)-X*(z*)]
C. 1/2[X(-z)-X*(z*)]
D. 1/2[X(-z)+X*(z*)]
Answer:A
If x(n) is an imaginary sequence, then the z-transform of the real part of the sequence is:
A. 1/2[X(z)+X*(z*)] B. 1/2[X(z)-X*(z*)] C. 1/2[X(-z)-X*(z*)] D. 1/2[X(-z)+X*(z*)]
Explanation: If x(N) is an imaginary sequence, then the real part of x(n) is given as
