Least-squares spectral analysis — (LSSA) is a method of estimating a frequency spectrum, based on a least squares fit of sinusoids to data samples, similar to Fourier analysis. [cite book | title = Variable Stars As Essential Astrophysical Tools | author = Cafer Ibanoglu |… … Wikipedia
Nyquist–Shannon sampling theorem — Fig.1: Hypothetical spectrum of a bandlimited signal as a function of frequency The Nyquist–Shannon sampling theorem, after Harry Nyquist and Claude Shannon, is a fundamental result in the field of information theory, in particular… … Wikipedia
Cheung–Marks theorem — In information theory, the Cheung–Marks theorem[1], named after K. F. Cheung and Robert J. Marks II, specifies conditions[2] where restoration of a signal by the sampling theorem can become ill posed. It offers conditions whereby reconstruction… … Wikipedia
Whittaker–Shannon interpolation formula — The Whittaker–Shannon interpolation formula or sinc interpolation is a method to reconstruct a continuous time bandlimited signal from a set of equally spaced samples. Contents 1 Definition 2 Validity condition 3 Interpolation as convolution sum … Wikipedia
Prony's method — Prony analysis (Prony s method) was developed by Gaspard Riche de Prony in 1795. However, practical use of the method awaited the digital computer [1] . Similar to the Fourier transform, Prony s method extracts valuable information from a… … Wikipedia
Root mean square — In mathematics, the root mean square (abbreviated RMS or rms), also known as the quadratic mean, is a statistical measure of the magnitude of a varying quantity. It is especially useful when variates are positive and negative, e.g., sinusoids.It… … Wikipedia
Signal reconstruction — In signal processing, reconstruction usually means the determination of an original continuous signal from a sequence of equally spaced samples.This article takes a generalized abstract mathematical approach to signal sampling and reconstruction … Wikipedia
