Bode Plot App
Read full descriptionHide full description
Bode Plot makes it easy to create Bode diagrams just by entering a transfer function. Visualize frequency response and compare multiple functions on the same graphs. Enter transfer functions, including complex expressions such as G(s)=100/(s*(s+1)^2). Gain (20log₁₀|G(jω)|) and phase (∠G(jω)) plots are generated automatically. Overlay multiple transfer functions in different colors to compare their gain and phase characteristics at a glance. Use sliders to adjust the frequency range and the number of plotted points. Your transfer functions are saved on your device so you can continue where you left off.
