two-range filter
1Filter design — is the process of designing a filter (in the sense in which the term is used in signal processing, statistics, and applied mathematics), often a linear shift invariant filter, which satisfies a set of requirements, some of which are contradictory …
2Two-dimensional nuclear magnetic resonance spectroscopy — (2D NMR) is a set of nuclear magnetic resonance spectroscopy (NMR) methods which give data plotted in a space defined by two frequency axes rather than one. Types of 2D NMR include correlation spectroscopy (COSY), J spectroscopy, exchange… …
3Filter (optics) — Coloured and Neutral Density filters Optical filters are devices which selectively transmit light of different wavelengths, usually implemented as plane glass or plastic devices in the optical path which are either dyed in the mass or have… …
4Filter binding assay — In biochemistry, one of the ways to learn about an interaction between two molecules is to determine the binding constant, which is a number that describes the ratio of unbound and bound molecules. This information reveals the affinity between… …
5Filter fluorometer — A filter fluorometer is a type of fluorometer that may be employed in fluorescence spectroscopy.FiltersThere are two filters for the fluorometer: #The primary filter or excitation filter or incident light filter isolates the wavelength that will… …
6Distributed element filter — Figure 1. A circuit featuring many of the f …
7Mechanical filter — Figure 1. A mechanical filter made by the Kokusai Electric Company intended for selecting the narrow 2 kHz bandwidth signals in SSB radio receivers. It operates at 455 kHz, a common IF for these receivers, and is dimensioned 45×15×15 mm ( …
8Photographic filter — Four photographic filters. Clockwise, from top left, an infrared hot mirror filter, a polarising filter, and a UV filter. The larger filter is a polariser for Cokin style filter mounts. In photography and videography, a filter is a camera… …
9Bloom filter — The Bloom filter, conceived by Burton H. Bloom in 1970, is a space efficient probabilistic data structure that is used to test whether an element is a member of a set. False positives are possible, but false negatives are not. Elements can be… …
10Atomic line filter — A potassium Faraday filter designed, built and photographed by Jonas Hedin for making daytime LIDAR measurements at Arecibo Observatory.[1] An atomic line filter (ALF) is an advanced optical band pass filter used in the physical sciences for… …
