Quadratic formula: Given az? + bz +c = 0, then z =
2a
The difference equation of an IIR filter is given by y[n] = -0.4y[n – 1] – 0.29y[n – 2] + x[n] – 1.6z[n – 1] + 0.73x[n – 2]. What are the zeros and
poles of the filter?
Select one:
Zeros={0.8 ± j0.3}, Poles={0.2 ± j0.5}
Zeros={0.8 ± j0.3}, Poles={-0.2± j0.5}
Zeros={-0.2± j0.5}, Poles={0.8 ± j0.3}
Zeros={-0.8+ j0.3}, Poles={0.2 + j0.5}
Zeros={0.8, 0.3}, Poles={0.7± j0.4}
