Shannon’s sampling theorem
Webb1 mars 1998 · Shannon’s sampling theorem is easier to show when applied to discrete-time sampling-rate conversion, i.e., when simple decimation of a discrete time signal is … The Whittaker–Shannon interpolation formula or sinc interpolation is a method to construct a continuous-time bandlimited function from a sequence of real numbers. The formula dates back to the works of E. Borel in 1898, and E. T. Whittaker in 1915, and was cited from works of J. M. Whittaker in 1935, and in the formulation of the Nyquist–Shannon sampling theorem by Claude Shannon in 1949. It is also commonly called Shannon's interpolation formula and Whittaker's inte…

Book excerpt: Advanced Topics in Shannon Sampling and Interpolation Theory is the second volume of a textbook on signal analysis solely devoted to the topic of sampling and restoration of continuous time signals and images. earthbikes.com.auThe Nyquist–Shannon sampling theorem is a theorem in the field of signal processing which serves as a fundamental bridge between continuous-time signals and discrete-time signals. It establishes a sufficient condition for a sample rate that permits a discrete sequence of samples to capture all the … Visa mer Sampling is a process of converting a signal (for example, a function of continuous time or space) into a sequence of values (a function of discrete time or space). Shannon's version of the theorem states: Visa mer When $${\displaystyle x(t)}$$ is a function with a Fourier transform $${\displaystyle X(f)}$$: Visa mer Poisson shows that the Fourier series in Eq.1 produces the periodic summation of $${\displaystyle X(f)}$$, regardless of $${\displaystyle f_{s}}$$ and $${\displaystyle B}$$. Shannon, however, only derives the series coefficients for the case Visa mer As discussed by Shannon: A similar result is true if the band does not start at zero frequency but at some higher value, and can be proved by a linear translation (corresponding physically to single-sideband modulation) of the zero-frequency case. In … Visa mer When there is no overlap of the copies (also known as "images") of $${\displaystyle X(f)}$$, the $${\displaystyle k=0}$$ term of Eq.1 can be recovered by the product: $${\displaystyle X(f)=H(f)\cdot X_{s}(f),}$$ where: Visa mer The sampling theorem is usually formulated for functions of a single variable.

INTRODUCTION THE sampling theorem is one of the most basic and fas-cinating topics in engineering sciences. The most well-known form is the uniform sampling theorem for bandlimited signals, due to Nyquist and Shannon [9], [13].
