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 ...

If we want to take samples of some analog waveform, as in doing analog to digital conversions at some particular conversion rate, there is an absolute lower limit to the rate of doing conversions ...

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

Primer on Nyquist and aliasing applied to the design of input filters for ADCs. Sampling a signal causes the original signal spectrum (blue) to create sum (purple) and difference (red) frequencies ...
