This idea details a design method for making anti-aliasing prefilter parameter tradeoffs between several factors. These factors include the filter pass-band magnitude accuracy, the filter order (the ...

In this DI, high school student Tommy Liu modifies a popular low-cost DIY oscilloscope to enhance its input noise rejection and ADC noise with anti-aliasing filtering and IIR filtering. Three ...

Several people asked for more information about anti-alias filters used with analog-to-digital converters to remove unwanted signals. This column describes a filter-selection "gotcha," and includes ...

One of the jobs of a circuit designer is to build a measurement system that provides valid input-to-output data as defined by the system requirements over a given frequency range. The four possible ...

Q: What is an anti-alias filter, and do I need one? A: At its simplest an anti-alias filter removes unwanted high-frequency signals from the signals you want to measure. Let's look at why you might ...

This article is part of the Ideas for Design Series: Vol. 3, No. 9. Many communications and sensor applications require a bandpass filter with wide bandwidth. This filter typically requires precision ...

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 ...

Qualcomm has taken a 2.64% stake in Sharp by buying 30m Sharp shares for $60m. The present intention is for Qualcomm to lift its stake to 5.2% via a similar deal in March, though Sharp says this ...

Previously on Digital Foundry we discussed how morphological anti-aliasing (MLAA) has evolved from a theory put together by Intel into a working technology for PlayStation 3, developed by Sony's ...

After revealing the feature nearly two years ago, Nvidia’s DLAA has slowly worked its way into a long list of games including Diablo IV, Baldur’s Gate 3, and Marvel’s Spider-Man. It’s an AI-driven ...
