BodeVisualiser

Interactive Bode plot visualiser with asymptote overlay.

Bode Visualiser

This app plots the exact Bode diagram alongside asymptote approximations for a given transfer function.

Features:

• Handles complex poles/zeroes and time delay
• Exact magnitude and phase curves
• Asymptote construction lines with slope annotations (dB/dec, °/dec) and break-frequency markers
• Pole/zero editor — add or remove real or complex-conjugate roots; plot updates automatically
• Datatip labels for poles/zeroes, breakpoints, and asymptote slopes

Usage:

Run
