In a world driven by digital signals, every piece of information begins as a continuous waveform.
But to process these signals, we must convert them… into discrete samples.
This is where sampling becomes critical.
According to the Nyquist criterion, the sampling frequency must be at least twice the signal frequency… to preserve the true nature of the signal.
Let us begin with a stable scenario.
Here, the sampling rate is sufficiently high.
The waveform is captured accurately.
