Fourier Transform Visualizer
Interactive visualization of the Fourier transform. Select a signal type, adjust parameters, and observe the frequency spectrum and Fourier series reconstruction.
Signal Parameters
1.0
2.0
10
Time Domain
The original signal waveform in the time domain.
Frequency Spectrum
Magnitude of the Fourier coefficients |X(f)| showing the signal's frequency content.
Fourier Series Reconstruction
Original signal (faded) vs. reconstruction using the first N harmonics. Increase N to see convergence.
