In mathematics, a filter on a set X {\displaystyle X} is a family B {\displaystyle {\mathcal {B}}} of subsets such that: X ∈ B {\displaystyle X\in {\mathcal...

local basis (or neighbourhood base or local base) for a point x {\displaystyle x} is a filter base of the neighbourhood filter; this means that it is a subset...

mathematics, a filter or order filter is a special subset of a partially ordered set (poset), describing "large" or "eventual" elements. Filters appear in...

A Bloom filter is a space-efficient probabilistic data structure, conceived by Burton Howard Bloom in 1970, that is used to test whether an element is...

of filter dryer consists of a main insulated jacketed vessel and filtration base which can be lowered for inspection and replacement of the filter media...

than those based on a single measurement alone, by estimating a joint probability distribution over the variables for each timeframe. The filter is constructed...

The Butterworth filter is a type of signal processing filter designed to have a frequency response that is as flat as possible in the passband. It is also...

In mathematics, the Fréchet filter, also called the cofinite filter, on a set X {\displaystyle X} is a certain collection of subsets of X {\displaystyle...

uniformities. Every filter is a prefilter and both are filter subbases. Every prefilter and filter subbase is contained in a unique smallest filter, which they...

Take a topological space X and a filter base B in that space. The set of all cluster points for that filter base is given by ⋂ { B ¯ 0 : B 0 ∈ B } {\displaystyle...

Chebyshev filters are analog or digital filters that have a steeper roll-off than Butterworth filters, and have either passband ripple (type I) or stopband...

A coffee filter is a filter used for various coffee brewing methods including but not limited to drip coffee filtering. Filters made of paper (disposable)...

In signal processing, a band-stop filter or band-rejection filter is a filter that passes most frequencies unaltered, but attenuates those in a specific...

A particulate air filter is a device composed of fibrous, or porous materials which removes particulates such as smoke, dust, pollen, mold, viruses and...

developed the mathematical theory on which the filter is based. The filters are also called Bessel–Thomson filters in recognition of W. E. Thomson, who worked...

Particle filters, or sequential Monte Carlo methods, are a set of Monte Carlo algorithms used to find approximate solutions for filtering problems for...

An all-pass filter is a signal processing filter that passes all frequencies equally in gain, but changes the phase relationship among various frequencies...
