Simulação interativa
Amostragem de ADC e aliasing
Amostre uma senoide devagar demais e veja o fantasma do alias aparecer.

Slow-motion live view (0.15x). Watch the red reconstruction collapse into a slow ghost sine when the signal frequency crosses the Nyquist limit (half the sample rate). Time is counted from the present sampling instant: 0 is now, at the right-hand edge, and the second already sampled runs to its left.
