The 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 $${\displaystyle X(f)}$$: $${\displaystyle X(f)\ \triangleq \ \int _{-\infty }^{\infty }x(t)\ e^{-i2\pi ft}\ {\rm {d}}t,}$$ the Visa mer The sampling theorem is usually formulated for functions of a single variable. Consequently, the theorem is directly applicable to … Visa mer The sampling theory of Shannon can be generalized for the case of nonuniform sampling, that is, samples not taken equally spaced in time. The Shannon sampling theory for … Visa mer When there is no overlap of the copies (also known as "images") of $${\displaystyle X(f)}$$, the Visa mer Poisson shows that the Fourier series in Eq.1 produces the periodic summation of $${\displaystyle X(f)}$$, regardless of Let 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.
