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 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 ...

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 ...

Every so often someone publishes an article discussing aliasing. I thought I’d jump on the bandwagon – you know, that one in the movies whose wheels seem to be rotating the wrong way. Is aliasing a ...

The integral role of software-defined radios in today's RF design. Why is an analog-to-digital converter such a key factor in SDRs? How to minimize SFDR to maximize ADC performance with a novel ...
