Filtre anti-repliement (anti-aliasing). Il est inutile et même nuisible d’imposer à un système de TNS des signaux dont les variations seraient plus rapides que ce. French term or phrase: filtre anti-repliement. This term crops up in a text on noise emissions in conjunction with an EU project. The “filter” is part. The categories of this image should be checked.

Often, an anti-aliasing filter is a low-pass filter ; this ant not a requirement, however. For the moment I prefer NOT to give “my” answer so as not to set you off on the wrong track.

The mathematics of sampling in two spatial dimensions is similar to the mathematics of time-domain sampling, but the filter implementation technologies are different.

For signals that are bandwidth limited, but not centered at zero, a band-pass filter can znti used as an anti-aliasing filter.

If one desired to sample an FM radio broadcast centered at The user can turn the vibration on or off, selecting anti-aliasing or no anti-aliasing. An alternative method is to use a digital anti-aliasing filter. View forum View forum without registering on UserVoice. This term crops up in a text on noise emissions in conjunction with an EU project. Retrieved November 29, View Ideas submitted by the community. The filter works by micro vibrating the sensor element.

When distortion due to clipping occurs after the anti-aliasing filter, it can create components outside the passband of the anti-aliasing filter; these components can then alias, causing the reproduction of other non- harmonically related frequencies.

This was also “my” answer and I needed confirmation of someone in the field. The Pentax K-3 from Ricoh introduced a unique sensor-based anti-aliasing filter. Because analog filters have relatively high cost and limited performance, relaxing the demands on the analog filter can greatly reduce both aliasing and cost.

How does one select the right filter? Generalizations of the Nyquist—Shannon sampling theorem allow sampling of other band-limited passband signals instead of baseband signals. Views Read Edit View history. Scientific photography and applied imaging. Term search Jobs Translators Clients Forums.

I think I know the answer to this from googling on filltre web but it would be nice if someone with technical knowledge could confirm.

This page was last edited on 17 Decemberat Alternatively, a signal may be intentionally oversampled without an intermediate frequency to reduce the requirements on the anti-alias filter. You will also have access to many other tools and opportunities designed for those who have language-related jobs or are passionate about them.


French term or phrase: Furthermore, because some noise is averaged out, the higher sampling rate can moderately improve SNR. Vote Promote or demote ideas. Login or register free and only takes a few minutes to participate in this question.

Bayer filter cameras, an additional filter is generally needed to reduce aliasing to an acceptable level. From Wikipedia, the free encyclopedia. Detection theory Discrete signal Estimation theory Nyquist—Shannon sampling theorem. By using this site, you agree ffiltre the Terms of Use and Privacy Policy. A technique known as oversampling is commonly used in audio Antu. It is very important to avoid input signal overload when using an anti-aliasing filter.

Return to KudoZ list. An anti-aliasing filter is a low-pass filter that accomplishes this.

An anti-aliasing filter AAF is a filter used before a signal sampler to restrict the bandwidth of a signal to approximately or completely satisfy the sampling theorem over the band of interest. You can request verification for native languages by completing a simple application that takes only a couple of minutes.
