ECE 210 Interactive Visuals

Supplementary demos for intuition and self-study.

Important: These visualizations are experimental and may contain mistakes or rough edges. Please use them as optional intuition-building aids, not as an authoritative source for definitions, notation, or grading expectations.

Available demos

The Angle Challenge
Practice angle representations and conversions.
Complex Numbers
Explore magnitude, phase, and geometric interpretation in the complex plane.
ZIR, ZSR, and Superposition
Interactive example illustrating zero-input response, zero-state response, and their sum.
Harmonics and Superposition
Build intuition for combining sinusoidal components.
Fourier Series Visualization
Visualize how Fourier series components combine to represent periodic signals.
Another Fourier Series Visualization
A second interactive view of Fourier series and signal reconstruction.
From Fourier Series to Fourier Transform
Develop intuition for the transition from discrete spectral lines to a continuous spectrum.
Interactive Convolution
Visualize how sliding, multiplying, and integrating produce convolution.
Another Interactive Convolution
A second convolution demo with a slightly different presentation.
Dirac Impulse and Sifting Property
Develop intuition for impulses, sampling, and the sifting property.
Impulse Response and Step Response
Explore the relationship between impulse response, step response, and system behavior.
Sampling, Reconstruction, and Aliasing
See how sampling rate affects reconstruction and aliasing behavior.
