A digital filter is defined by its poles and zeros in the z-plane. A pole near the unit circle creates a resonant peak at its angle; a zero on the circle carves a notch. Move them and watch the frequency response reshape. Educational tool.

Governing equation

H (z) = \frac{( z - e ^{j 12 0^{\circ}} ) ( z - e ^{- j 12 0^{\circ}} )}{( z - 0.85 e ^{j 4 5^{\circ}} ) ( z - 0.85 e ^{- j 4 5^{\circ}} )}, stable ⟺ ∣ p ∣ = 0.85 < 1

Reading this result: A pole at r=0.85, 45° gives a resonant peak while the zero at 120° carves a separate notch — a classic two-feature filter.

About this simulation

The full Pole–Zero Response tool models a PCB trace with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.
