Nyquist–Shannon sampling theorem - Wikipedia, the free encyclopedia The Nyquist–Shannon sampling theorem is the fundamental theorem in the field of information theory, in particular telecommunications. A well-known consequence of the sampling theorem is that a signal cannot be both bandlimited and time-limited. Although the theorem states that the sampling rate must be twice the bandwidth, it can readily be seen that this proof still holds. www.wikipedia.org /wiki/Nyquist-Shannon_sampling_theorem

Nyquist frequency The frequency f/2 is known as the Nyquist frequency, in reference to the Nyquist-Shannon sampling theorem. In telecommunication, the Nyquist frequency is the minimum theoretical sampling rate that fully describes a given signal, i.e., enables its faithful reconstruction from the samples. For example, an audio CD with a sampling frequency of 44100 Hz cannot reproduce frequencies higher than 22050 Hz if the lowest frequency to be sampled is 0 Hz. www.theezine.net /n/nyquist-frequency.html

Talk:Nyquist–Shannon sampling theorem - Wikipedia, the free encyclopedia This is in fact the Nyquist-Shannon sampling theorem (and we could write it explicitly sort of the way it's written, although I suspect there's an off-by-one bug in the current statement.) With this presumption, the Nyquist-Shannon interpolation formula follows. In the end, the point of the sampling theorem is to contain all the energy of the signal in the frequencies under the nyquist frequency. This is related to but not the same as the Nyquist sampling theorem. en.wikipedia.org /wiki/Talk:Nyquist-Shannon_sampling_theorem

1999 Sophomore College Project Shannon came up with the sampling theorem when he needed to find a solution to the problem of how computers can handle a continuous analogue signal. Shannon realized that the sampling frequency has to be at least twice the absolute maximum frequency of the continuous signal. This sampling frequency is also called the Nyquist frequency. cse.stanford.edu /class/sophomore-college/projects-99/information-theory/math.html

Shannon's sampling theorem Whenever Shannon's sampling theorem is not fulfilled, aliasing occurs. (Claude E. Shannon, born 1916, American mathematician), also known as the Nyquist criterion, a general "rule" for measurement of frequencies, stating that the measurement (sampling) frequency must be at least twice the maximum frequency to be measured. In radiology, Shannon's sampling theorem must be considered in e.g. www.amershamhealth.com /medcyclopaedia/Volume%20I/Shannons%20sampling%20theorem.html

The Ultimate Digital sampling - American History Information Guide and Reference Digital sampling is the recording, playback, looping and editing of sound in a musical context using a computer to convert the sound into a series of numbers representing the measurement of the amplitude of the sound. The highest frequency in the original sound that can be represented by the samples at a given sample rate without a kind of distortion known as aliasing is limited to half the sampling rate. The measurement or "sample" is taken at a regular interval. www.historymania.com /american_history/Digital_sampling

Nyquist The sampling theorem is considered to have been articulated by Nyquist in 1928 and mathematically proven by Shannon in 1949. The Nyquist sampling theorem showed that the sampling rate must be at least twice the highest frequency present in the sample in order to reconstruct the original signal. This became known as the Nyquist frequency, which is the highest frequency that may be accurately sampled, and is one-half of the sampling frequency. www.geocities.com /bioelectrochemistry/nyquist.htm

Learning by Simulations: Sampling Theorem The Nyquist-Shannon sampling theorem is a fundamental theorem in the field of information theory which has considerable effects on many aspects of modern technology (i.e. The sampling theorem states that, when sampling a signal (i.e, converting from analog to digital), the sampling frequency must be greater than twice the bandwidth of the input signal in order to be able to reconstruct the original signal from the sampled version: This simulation shows the consequences of the sampling theorem. www.vias.org /simulations/simusoft_nykvist.html

Olympus Microscopy Resource Center: Digital Image Processing Interactive Java Tutorials Digital Image Sampling Frequency - In order to match the optical and electronic resolution of a microscope and the accompanying camera system, a digital image should have a sufficient number of samples per horizontal line so that the display faithfully represents the original signal presented to the digitizing device. The effects of this common image defect can be minimized with proper sampling of the specimen image by gathering an adequate number of pixels at the proper spatial resolution during capture. This interactive tutorial examines how variations in specimen sampling frequency affect the resolution of the final image. www.olympusmicro.com /primer/digitalimaging/javaindex.html

Articles - Sampling frequency The Nyquist-Shannon sampling theorem states that the sampling frequency has to be greater than twice the Nyquist frequency or, equivalently, twice the bandwidth of the signal being sampled. In some cases, it is desirable to have a sampling frequency more than twice the bandwidth so that a digital filter can be used in exchange for a weaker analog anti-aliasing filter. All modern TV cameras use CCDs, and the image sampling frequency is the repetition rate of the CCD integration period. www.gaple.com /articles/Sampling_rate

Nyquist-Shannon - Wikipedia A fundamental tenet in the field of Information Theory, the Nyquist-Shannon Sampling Theorem states that, when converting from an analog signal to digital, the sampling frequency must be greater than twice the highest frequency of the input signal in order to reconstruct the original perfectly.

Shannon/Nyquist Sampling and Reconstruction Theorem if the former, things like the sampling theorem should be nearly trivial for guys like you with brains the size of small planets. if not, and you feel obliged to be truly mathematically rigorous with the dirac-delta function, then, maybe you're right, the sampling theorem would be pretty hard to do. In general, Shannon 1948 is astonishingly clear (even > fifty years on, in many ways it is still the best short introduction to > his information theory), but the "proofs" in this paper tend toward the > heuristic rather than the rigorous. www.lns.cornell.edu /spr/2002-08/msg0043466.html

Bandlimited - Art History Online Reference and Guide This result is known as the sampling theorem, and usually attributed to Nyquist or Shannon and referred to as Nyquist-Shannon Sampling Theorem. This has the consequence that the signal can be fully reconstructed from its samples, provided that the sampling frequency is at least twice as much as the maximum frequency in the bandlimited signal. This critical frequency is also referred to as the Nyquist frequency. www.arthistoryclub.com /art_history/Bandlimited
