Bode Plot Approximator

Input poles and zeros to draw asymptotic Bode magnitude/phase curves for quick control design estimation.

Gain K (Linear) ω Min (rad/s) ω Max (rad/s) Sample Points Zeros at Origin (order) Poles at Origin (order) Zero Break Frequencies (rad/s) Pole Break Frequencies (rad/s)

Supports comma / space / newline separators (e.g. "1, 10 100"). This tool draws classic straight-line magnitude and piecewise phase approximations.
