I have been asked to sketch the Z planes poles and zeros for the follwoing:
H(z) = ((z-1)^2 (z+1)^2) /(z-0.7)(z+0.9+0.95j)(z+0.9-0.95j)
I have the denominator points sorted. Would the numerator points be:
(z-1)^2 =0
z-1 =0
z=1
and
(z+1)^2 = 0
z+1 = 0
z = -1
H(z) = ((z-1)^2 (z+1)^2) /(z-0.7)(z+0.9+0.95j)(z+0.9-0.95j)
I have the denominator points sorted. Would the numerator points be:
(z-1)^2 =0
z-1 =0
z=1
and
(z+1)^2 = 0
z+1 = 0
z = -1
