Aliasing is thankfully becoming a less frequent problem due to improved instrument designs. Users should still be aware of it ...

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 ...

The old-fashioned method of antialiasing is called super sampling. An image that is 800x600 is upscaled by, for example, 4 times, to make an image that is 1600x1200 inside the graphics processor. Each ...

Sampling a signal causes the original signal spectrum (blue) to create sum (purple) and difference (red) frequencies around the sampling frequency, fS. When the difference signals fall into the ...
