filter phase response

  • 1Phase response — is the relationship between the phase of a sinusoidal input and the output signal passing through any device which accepts input and produces an output signal such as an amplifier or a filter.Amplifiers, filters and other devices are often… …

  • 2Filter 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 …

  • 3Phase distortion — In signal processing, phase distortion or phase frequency distortion is distortion that occurs when (a) a filter s phase response is not linear over the frequency range of interest, that is, the phase shift introduced by a circuit or device is… …

  • 7Finite impulse response — A finite impulse response (FIR) filter is a type of a digital filter. The impulse response, the filter s response to a Kronecker delta input, is finite because it settles to zero in a finite number of sample intervals. This is in contrast to… …
