Laplace Transform Visualizer

s-plane, poles, zeros, and frequency response

F(s) = ∫₀^∞ f(t)e⁻ˢᵗ dt  |  s = σ + iω
s-plane (poles × zeros ○)
Frequency Response |F(iω)|
The s-plane shows poles (×) and zeros (○). Poles in the left half-plane → stable system. The imaginary axis (σ=0) is where the Laplace transform reduces to the Fourier transform. Drag the probe point to explore |F(s)| across the complex plane. The frequency response shows |F(iω)| along the imaginary axis.
