band-pass filter — /ˈbænd pas fɪltə/ (say band pahs filtuh) noun (in electronics) an electrical network which allows only signals with frequencies between certain values, which may be fixed or variable, to pass. See high pass filter, low pass filter …
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
Electronic filter — Electronic filters are electronic circuits which perform signal processing functions, specifically intended to remove unwanted signal components and/or enhance wanted ones. Electronic filters can be:*passive or active *analog or digital *discrete … Wikipedia
Active filter — An active filter is a type of analog electronic filter, distinguished by the use of one or more active components i.e. voltage amplifiers or buffer amplifiers. Typically this will be a vacuum tube, transistor or operational amplifier.Active… … 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

Electronic filter topology — An elementary filter topology introduces a capacitor into the feedback path of an op amp to achieve an unbalanced active implementation of a low pass transfer function Electronic filter topology defines electronic filter circuits without taking… … Wikipedia
Equalization filter — An equalization (EQ) filter is a filter, usually adjustable, chiefly meant to compensate for the unequal frequency response of some other signal processing circuit or system. An EQ filter typically allows the user to adjust one or more parameters … Wikipedia
Digital filter — A general finite impulse response filter with n stages, each with an independent delay, di, and amplification gain, ai. In electronics, computer science and mathematics, a digital filter is a system that performs mathematical operations on a… … Wikipedia
State variable filter — A state variable filter is a type of active filter. It consists of one or more integrators, connected in some feedback configuration. Any LTI system can be described as a state space model, with n state variables for an nth order system. A state… … Wikipedia
State variable topology — refers to filters with two pole filter topology. State variable filters are available in lowpass, highpass, bandpass, and notch versions. The notch version is not recommended, because it requires too many amplifiers. It is one of three topologies … Wikipedia
