Previous articles in Planet Analog make mention of the “aliasing effect.” Most EEs agree in the importance of the aliasing effect as a noise source and take for granted that anti-aliasing filters are ...

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 ...

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 ...

(1) Smoothing a distorted communications signal by applying techniques that add data or filter out unwanted noise. (2) Smoothing the jagged appearance of diagonal lines in a bitmapped image. The ...

When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. One of the fundamental processes involving digital signals is sampling. When sampling video and ...

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 ...

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 ...

Back when the GeForce RTX family launched in late 2018, NVIDIA unveiled its Deep Learning Super Sampling anti-aliasing method, which upscales low-resolution images via machine learning on the GPU's ...
