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 ...

In part 1, we started to make some intuitive connections between near-Nyquist sampling, the addition of close-frequency sines, and how those signals would interact with perfect LP filters. Let's put ...

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 ...

With the growing use of multiple video formats, a fundamental understanding of sampling rate conversion will provide insight into the quality and operation of format converters. However, before ...

Anti-aliasing smooths the raw and haggard edges on digital type and images on computer and handheld displays, wireless phones, printers, even digital cameras. Aliasing – jagged or stair-stepped edges ...

NVIDIA's transparency anti-aliasing uses sub-pixel samples to anti-alias alpha-textures. NVIDIA support it in G70 using both multi-sampling (depth samples) and super-sampling (texture samples) using ...
