A look at the Nyquist sampling theorem. How to deal with aliasing by attenuating signals using low-pass filters (i.e., an antialiasing filter, or AAF). AAF requirements for different ADCs. A deep dive ...

Bravo to Harry Nyquist and Claude Shannon! In the 1920s, these gentlemen created the now-well-known Nyquist theorem, which states that when sampling a signal at discrete intervals, the sampling must ...

This project is a desktop application developed to demonstrate the principles of signal sampling and recovery based on the Nyquist–Shannon sampling theorem. It helps users visualize, sample, and ...

In part 1, we started to make some intuitive connections between near-Nyquist sampling, the addition of close-frequency sines, and how those signals would interact with perfect LP filters. Let's put ...

Abstract: As electromagnetic environments become increasingly complex, the demand for ultra-wideband signal reception has become more widespread. Traditional Nyquist sampling theorem requires high ...
