Analogue to Digital Conversion [PART 3 – Aliasing]

Aliasing is a phenomenon that occurs when sampling analogue signals with high frequency components. When sampling at a frequency lower than the Nyquist frequency, signals may be incorrectly detected at a lower frequency, leading to inaccurate results. Careful design and… Continue
