"Pole-zero plot on the complex plane with a unit circle, showing quantised and reference zeros (circular markers) overlapping and clustered vertically near real part minus one, imaginary part zero, and quantised and reference poles (plus-sign and cross markers) clustered nearby, slightly to the right, indicating close agreement between quantised and reference filter values."
