2. Waveform Confusion: when the sample rate is lower than twice the actual
signal frequency (Nyquist Frequency), the frequency of the waveform rebuilt
from the sample data is lower than the actual signal frequency.
3. Waveform Leakage: when the sample rate is too low, the waveform rebuilt
from the sample data does not reflect the actual signal completely.
