๐ What Is a Fourier Transform?
The Fourier Transform breaks a signal into its frequency components. Any complex waveform can be rewritten as a sum of sine and cosine waves.
- It helps us understand the **frequency content** of signals
- The animation shows both the **original waveform** and its **spectrum**
- Use the sliders to mix two frequencies and see their breakdown!

๐ข Galois Field Transform (GFT)
This GFT operates over finite fields GF(p), using modular arithmetic and primitive roots to simulate frequency-domain transformations.
