Sampling TheoremDespite digital techniques for data acquisition and processing being widely used in biomedical research for quite some time, inappropriate signal conditioning and digitization are still potential
2.9 The Sampling Theorem Sampling is necessary for the processing of analog data using digital elements. Successful digital data processing requires that the samples reflect the nature of the analog signal and that analog signals be recoverable, at least in theory, from a sequence of samples. Figur...
Sampling theorem for angularly periodic functions bandlimited both to highest frequency and in the LCHT domain Combining Lemma 4, Lemma 5 yields an interpolation formula that interpolates in both radius and azimuth the function with limited bandwidth in the LCHT domain and limited highest frequency....
The Nyquist–Shannon sampling theorem is perhaps the most impactful result in the theory of signal processing, fundamentally shaping the practice of acquiring and processing data [1, 2] (also attributed to Kotel’nikov [3], Ferrar [4], Cauchy [5], Ogura [6], Whittaker [7, 8]). In thi...
Sampling Theorem 原始字幕仅供学习 [图片] To simplify our understanding of the conversion from analog to digital signals, we’ll start from the simplest periodic analog signal, the humble sine wave. We had previously derived the sine wave function, and it

Oversampling is widely used in practical applications of digital signal processing. As the fractional Fourier transform has been developed and applied in signal processing fields, it is necessary to consider the oversampling theorem in the fractional Fourier domain. In this paper, the oversampling ...
Nyquist–Shannonsampling theoremX ( ƒ) 1 IntroductionSampling is the process of converting a signal (for ex-ample, a function of continuous time and/or space) intoa numeric sequence (a function of discrete time and/orspace). Shannon’s version of the theorem states: [1]−B B ƒIf...
In digital audio the most common sampling rates are 44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz and 192 kHz.[5] Lower sampling rates have the benefit of smaller data size and easier storage and transport. Because of the Nyquist-Shannon theorem, sampling rates higher than about 50 kHz to 60 kHz...
