filter phase response
11Variable fractional delay filter — Introduction= One important advantage of the variable digital filter is that the frequency characteristics, including the magnitude response and the phase response are tunable without re implementation of the filter. Variable fractional delay… …
12Constant k filter — Linear analog electronic filters Network synthesis filters Butterworth filter Chebyshev filter Elliptic (Cauer) filter Bessel filter Gaussian filter Optimum L (Legendre) filter Linkwitz Riley filter …
13Digital 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… …
14Linkwitz-Riley filter — A Linkwitz Riley (L R) filter is an infinite impulse response filter used in Linkwitz Riley audio crossovers, named after its inventors Siegfried Linkwitz and Russ Riley, which was originally described in Passive Crossover Networks for… …
15Reconstruction filter — In a mixed signal system (analog and digital), a reconstruction filter (or anti imaging filter) is used to construct a smooth analogue signal from the output of a digital to analogue converter (DAC) or other sampled data output device.ampled data …
16Low-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 …
17Minimum phase — In control theory and signal processing, a linear, time invariant system is said to be minimum phase if the system and its inverse are causal and stable.[1][2] For example, a discrete time system with rational transfer function H(z) can only… …
18Group delay and phase delay — Group delay is a measure of the time delay of the amplitude envelopes of the various sinusoidal components of a signal through a device under test, and is a function of frequency for each component. Phase delay is a similar measure of the time… …
19Cascaded integrator-comb filter — In digital signal processing, a cascaded integrator comb (CIC) is an optimized class of finite impulse response filter combined with an interpolator or decimator. [Donadio, Matthew (2000) [http://www.dspguru.com/info/tutor/cic.htm CIC Filter… …
20Linear phase — is a property of a filter, where the phase response of the filter is a linear function of frequency, excluding the possibility of wraps at pmpi. In a causal system, perfect linear phase can be achieved with a discrete time FIR filter.Since a… …
