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.

Replifment Pentax K-3 from Ricoh introduced a unique sensor-based anti-aliasing filter. If the signal is strong enough, it can cause clipping at the analog-to-digital convertereven after filtering.
French PRO pts in category: Retrieved November 29, Views Read Edit View history. Because analog filters have relatively high cost and limited performance, relaxing the demands on the analog filter can greatly reduce both aliasing and cost. You should have given confidence of 5: You can request verification for native languages by completing a simple application that takes only a couple of minutes.

Often, an anti-aliasing filter is a low-pass filter ; this is not repliemejt requirement, however. Furthermore, because some noise is averaged out, the higher sampling rate can moderately improve SNR. Digital signal processing Linear filters Electronic filter applications Anti-aliasing. The filter works by micro vibrating the sensor element. Grading comment 4 KudoZ points were awarded for this answer.

For signals that are bandwidth limited, but not centered at zero, a band-pass filter can be used as an anti-aliasing filter. For example, this could be done with a single-sideband modulated or frequency modulated signal.
Handbook of Image Quality: An anti-aliasing filter is a low-pass filter that accomplishes this. Retrieved from ” https: Peer comments on this answer and responses from the answerer agree.

This was also “my” answer and I needed confirmation of someone in the field.
The KudoZ network provides a framework for translators and others to assist each other with translations or explanations of terms and short phrases. The mathematics of sampling in two spatial dimensions is similar to the mathematics of time-domain sampling, but the filter implementation technologies are different. Since the theorem states that, unambiguous reconstruction of the signal from its samples is possible when the power of frequencies above the Nyquist frequency is zero, a real anti-aliasing filter trades off between bandwidth and aliasing.
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. Vote Promote or demote ideas.
