Filter 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 … Wikipedia
Filter (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… … Wikipedia
Low-pass filter — A low pass filter is a filter that passes low frequency signals but attenuates (reduces the amplitude of) signals with frequencies higher than the cutoff frequency. The actual amount of attenuation for each frequency varies from filter to filter … Wikipedia
Hodrick-Prescott filter — The Hodrick Prescott filter is a mathematical tool used in macroeconomics, especially in real business cycle theory. It is used to obtain a smoothed non linear representation of a time series, one that is more sensitive to long term than to short … Wikipedia
Hodrick-Prescott (HP) Filter — A data smoothing technique that is commonly applied to remove short term fluctuations that are associated with the business cycle, thereby revealing long term trends. The HP filter is used to determine the long term trend of a time series by… … Investment dictionary
