Step Response Explorer

Explore the relationship between the step-response of the system and the its pole/zero locations!

Welcome to the Interactive Pole-Zero Step-Response Analyzer!

This tool lets you explore the relationship between root locations on the complex plane and the resulting time-domain step response (assuming a DC Gain of 1).

HOW TO USE: • Add Roots: Go to Add -> Pole(s)/Zero(s), then click on the graph. • Move Roots: Left-click and drag any root to change its location. • Delete Roots: Right-click on a root to remove it.

METRICS: The top row shows the actual simulated metrics (via the stepinfo command). The bottom row calculates the "back-of-the-napkin" textbook estimates based on the dominant estimates based on the dominant pole(s) to help you see when those approximations hold true!
