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 ...

Nyquist-sampling theory lies at the heart of today's digital-communications systems. It requires that data-conversion systems include antialiasing input filters. Designers need to understand the ...

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 ...

When you digitize an analog signal, you use a lowpass filter to prevent aliasing errors from out-of-band noise. Doing so attenuates superimposed, high-frequency noise on the analog signal before it ...

How to decide between buffered and un-buffered (switched capacitor), high-speed analog-to-digital converters, with an example of anti-aliasing filter design. The fundamental end goal when using an ADC ...

The 3D games we play and love are all made up of thousands, if not millions, of colored straight lines and other edges. And because of the way that these appear on your screen, they can often look ...
