## Fourier App Description
Fourier App is an interactive tool for visualizing and computing Fourier Series of piecewise functions.

Define custom functions with multiple pieces and discontinuities, choose the time window, and instantly see the original signal x(t) alongside its series approximation s(t).

Browse a built-in catalog with classic examples like sine, cosine, step function, rectangular, triangular, ramp, parabola, and more.

View the frequency spectrum with an, bn, and cn coefficients, filter partial series terms, and explore how each harmonic contributes to the final waveform.

Includes a theory section covering Fourier Series history, equations, and real-world applications such as audio streaming and noise cancellation.
