Sinusoidal model — In statistics, signal processing, and time series analysis, a sinusoidal model to approximate a sequence Yi is::Y i = C + alphasin(omega T i + phi) + E i where C is constant defining a mean level, α is an amplitude for the sine wave, ω is the… … Wikipedia
sinusoidal wave — (Mathematics) wave that has the shape of a sinusoid, oscillatory curve describing a sine (the amplitude varies as the function y=a sin x) … English contemporary dictionary
Wigner distribution function — The Wigner distribution function (WDF), named after Eugene Wigner, was first proposed for corrections to classical statistical mechanics in 1932 by Eugene Wigner. But the Wigner distribution function is also a good transform for time frequency… … Wikipedia
Describing function — The Describing function (DF) method of Nikolay Mitrofanovich Krylov and Nikolay Bogolyubov is an approximate procedure for analyzing certain nonlinear control problems. It is based on quasi linearization, which is the approximation of the non… … 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
Window function — For the term used in SQL statements, see Window function (SQL) In signal processing, a window function (also known as an apodization function or tapering function[1]) is a mathematical function that is zero valued outside of some chosen interval … Wikipedia
Mathieu function — In mathematics, the Mathieu functions are certain special functions useful for treating a variety of problems in applied mathematics, including vibrating elliptical drumheads, quadrupoles mass filters and quadrupole ion traps for mass… … Wikipedia
