From description to signal

A short impulse can look precise in time while spreading across many frequencies. This lab lets you inspect both views without pretending the model is a live measurement.

Shape the signal. Read the spectrum.

256 samples across two seconds at a 128 Hz sample rate.

Read the shape, not a story.

What is calculated?

A synthetic baseline sine wave, Gaussian-windowed high-frequency impulses, and a direct discrete Fourier transform. Your exported CSV contains the exact samples and magnitudes shown.

What is not claimed?

This page does not monitor the Earth, reproduce a scientific instrument, identify causes, or support claims about health, consciousness, energy codes, or spiritual effects.

Why use a Fourier transform?

It separates a signal into frequency components. A brief event often occupies a narrow interval in time but a wider range in frequency, which is the central idea this model demonstrates.
