With rapid advancement in data acquisition technology (i.e.analog-to-digital and digital-to-analog converters) and the explosive introduction of micro-computers, selected complex linear and nonlinear ...

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 ...

We're living the audiophile dream! Our phones can hold a year's worth of music and stream more songs than anyone could listen to in a lifetime. But none of that would be possible without the efforts ...

It is shown that a well-known irregular sampling formula for ordinary bandlimited functions is also valid for functions bandlimited in a generalized sense, except for some necessary modifications.

The optional sampling theorem for martingales indexed by a partially ordered set is true if the index set is directed. However, the corresponding result for submartingales indexed by a partially ...

Scattering-type scanning near-field optical microscopy (s-SNOM) allows spectroscopic imaging with spatial resolution below the diffraction limit. With suitable light sources, s-SNOM is instrumental in ...

A research team at POSTECH has developed a novel multidimensional sampling theory to overcome the limitations of flat optics.

Mathematics has long been accepted as a tool to model the physical reality. For many it is hard to grasp that math actually “does something.” The reality is that mathematics based instructions in ...
