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
Step-by-step description of hemodialysis — Starting hemodialysis is often a frightening experience. Hemodialysis machines are complicated and dialysis sessions often are punctuated by alarms. At the beginning of dialysis and at the end of dialysis a lot of things happen. Not knowing what… … Wikipedia
Filter graph — A filter graph is used in multimedia processing. For example to capture video from a webcam. Filters take input, process it or change the input, and then output the process data. An example of a filter, would be a video codec that takes raw… … Wikipedia
Kalman filter — Roles of the variables in the Kalman filter. (Larger image here) In statistics, the Kalman filter is a mathematical method named after Rudolf E. Kálmán. Its purpose is to use measurements observed over time, containing noise (random variations)… … Wikipedia
Least mean squares filter — Least mean squares (LMS) algorithms are a class of adaptive filter used to mimic a desired filter by finding the filter coefficients that relate to producing the least mean squares of the error signal (difference between the desired and the… … Wikipedia
Particle filter — Particle filters, also known as sequential Monte Carlo methods (SMC), are sophisticated model estimation techniques based on simulation. They are usually used to estimate Bayesian models and are the sequential ( on line ) analogue of Markov chain … Wikipedia
Distributed element filter — Figure 1. A circuit featuring many of the f … Wikipedia
The Great Filter — is an implication of the failure to observe any extraterrestial life, despite considerable effort (the Fermi paradox). One possible explanation is that there is something, the Great Filter, which acts to reduce the great number of potential sites … Wikipedia
Causal filter — In signal processing, a causal filter is a linear and time invariant causal system. The word causal indicates that the filter output depends only on past and present inputs. A filter whose output also depends on future inputs is acausal. A filter … Wikipedia
Deblocking filter (video) — A deblocking filter is a video filter applied to blocks in decoded video to improve visual quality and prediction performance by smoothing the sharp edges which can form between macroblocks when block coding techniques are used. The filter aims… … Wikipedia
