What are poles and zeros of a system having following transfer function?
$$H\left( z \right) = \frac{{\left( {1 - {z^{ - 2}}} \right)}}{{\left( {1 + 1.3{z^{ - 1}} + 0.36{z^{ - 2}}} \right)}}$$
A. Zeros = -1, 1; poles = -0.4, -0.9
B. Zeros = -1, 1; poles = 0.4, 0.9
C. Zeros = 1; poles = 0.4, 0.9
D. Zeros = 1, 1; poles = 0.4, 0.9
