1 Answer. Sorted by: 1. Just multiply numerator and denominator by z2 z 2 to obtain. H(z) = z2 (z − 1 2)(z − 2) H ( z) = z 2 ( z − 1 2) ( z − 2) from which you see that there's a double zero at z = 0 z = 0. Note that the number of zeros and poles is always equal if you include poles and zeros at infinity. Share.
