The concept behind digitizing sound. Working at Bell Labs, Harry Nyquist discovered that it was not necessary to capture the entire analog waveform, and samples of the wave could be taken at ...

A research team at POSTECH has developed a novel multidimensional sampling theory to overcome the limitations of flat optics. Their study not only identifies the constraints of conventional sampling ...

For decades, researchers have relied on the Nyquist sampling theorem to predict and mitigate aliasing. However, the POSTECH team discovered that Nyquist’s theorem, while useful for digital ...
