Group 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… … Wikipedia
Differential group delay — In optics, differential group delay is the difference in propagation time between the two eigenmodes X and Y polarizations. Consider two eigenmodes that are the 0° and 90° linear polarization states. If the state of polarization of the input… … Wikipedia
Linear 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… … Wikipedia
Linear filter — A linear filter applies a linear operator to a time varying input signal. Linear filters are very common in electronics and digital signal processing (see the article on electronic filters), but they can also be found in mechanical engineering… … Wikipedia

Minimum 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… … Wikipedia
Distortion — This article is about technology, especially electrical engineering. For other uses, see Distortion (disambiguation). Distort redirects here. For other uses, see Distort (disambiguation). A distortion is the alteration of the original shape (or… … Wikipedia
Transfer function — A transfer function (also known as the system function[1] or network function) is a mathematical representation, in terms of spatial or temporal frequency, of the relation between the input and output of a linear time invariant system. With… … Wikipedia
Bessel filter — In electronics and signal processing, a Bessel filter is a variety of linear filter with a maximally flat group delay (linear phase response). Bessel filters are often used in audio crossover systems. Analog Bessel filters are characterized by… … Wikipedia
Soliton (optics) — In optics, the term soliton is used to refer to any optical field that does not change during propagation because of a delicate balance between nonlinear and linear effects in the medium. There are two main kinds of solitons: spatial solitons:… … 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
