The pole-zero diagram of a causal and stable discrete-time system is shown in the figure. The
zero at the origin has multiplicity 4. The impulse response of the system is h[n]. If h[0] = 1,
we can conclude
  • a)
    h[n] is real for all n
  • b)
    h[n] is purely imaginary for all n
  • c)
    h[n] is real for only even n
  • d)
    h[n] is purely imaginary for only odd n
Correct answer is option 'C'. Can you explain this answer?

Since poles are present on both sides it will be real
as 4 is multiplied in the center it will be even
hence c
