Download or read book Nonuniform Sampling written by Farokh Marvasti and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 938 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our understanding of nature is often through nonuniform observations in space or time. In space, one normally observes the important features of an object, such as edges. The less important features are interpolated. History is a collection of important events that are nonuniformly spaced in time. Historians infer between events (interpolation) and politicians and stock market analysts forecast the future from past and present events (extrapolation). The 20 chapters of Nonuniform Sampling: Theory and Practice contain contributions by leading researchers in nonuniform and Shannon sampling, zero crossing, and interpolation theory. Its practical applications include NMR, seismology, speech and image coding, modulation and coding, optimal content, array processing, and digital filter design. It has a tutorial outlook for practising engineers and advanced students in science, engineering, and mathematics. It is also a useful reference for scientists and engineers working in the areas of medical imaging, geophysics, astronomy, biomedical engineering, computer graphics, digital filter design, speech and video processing, and phased array radar.
Download or read book On the Reconstruction of Bandlimited Signals from Sampled Values written by Nassar Dastrange and published by . This book was released on 1973 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: The sampling theorem states that any frequency bandlimited signal can be exactly reconstructed from its sampled values. Different forms of this theorem have been reviewed since 1841 up to the present time. Kramer's generalized sampling theorem has been extended to two dimensions, and the form for higher dimensions can be derived by the same method. Upper bounds for the variations of sampled signals were investigated, and it was shown that tighter bounds can be established. Although the sampling theorem for sequency bandlimited signals was proved by the aid of Kramer's generalized sampling theorem we showed that this theorem can be proved directly or by the method of Shannon's sampling theorem in Fourier analysis. This is in agreement with the result of Campbell, that for some cases Kramer's generalized theorem does not enlarge the class of functions to which sampling theorems can be applied. Because of the recent interest in applications of sampling theorems in discrete and finite Walsh-Fourier analysis we introduced new forms of these theorems and proved them by simple techniques. These results were applied easily for the development of periodic and nonperiodic sampling theorems for two dimensions. Finally, a definition in Haar-Fourier analysis is created, which is analogous to the definition of M-sequency bandlimited signals. Based on this definition several useful theorems are established which show similarities between sampling theorems in Walsh and Haar-Fourier analysis.

Download or read book Digital Alias free Signal Processing written by Ivars Bilinskis and published by John Wiley & Sons. This book was released on 2007-09-27 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: As demand for applications working in extended frequency ranges increases, classical Digital signal processing (DSP) techniques, not protected against aliasing, are becoming less effective. Digital alias-free signal processing (DASP) is a technique for overcoming the problems of aliasing at extended frequency ranges. Based on non-uniform or randomised sampling techniques and the development of novel algorithms, it creates the capacity to suppress potential aliasing crucial for high frequency applications and to reduce the complexity of designs. This book provides practical and comprehensive coverage of the theory and techniques behind alias-free digital signal processing. Key features: Analyses issues of sampling, randomised and pseudo-randomised quantisation and direct and indirectly randomised sampling. Examines periodic and hybrid sampling, including information on processing algorithms and potential limitations imposed by signal dynamics. Sets out leading methods and techniques for complexity reduced designs, in particular designs of large aperture sensor arrays, massive data acquisition and compression from a number of signal sources and complexity-reduced processing of non-uniform data. Presents examples of engineering applications using these techniques including spectrum analysis, waveform reconstruction and the estimation of various parameters, emphasising the importance of the technique for developing new technologies. Links DASP and traditional technologies by mapping them into embedded systems with standard inputs and outputs. Digital Alias-free Signal Processing is ideal for practising engineers and researchers working on the development of digital signal processing applications at extended frequencies. It is also a valuable reference for electrical and computer engineering graduates taking courses in signal processing or digital signal processing.
Download or read book Periodic Signals Reconstruction of Undersampled written by Anthony Joseph Silva and published by . This book was released on 1986 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: Under certain conditions, a periodic signal of unknown fundamental frequency can still be recovered when sampled below the Nyquist rate, or twice the highest frequency present in the waveform. A new sampling criterion has been proposed which enumerates such conditions. It has been shown that in theory, if the signal and sampling frequencies are not integrally related, and the signal is band-limited (to a range the extent of which is known but otherwise unrestricted), then the signal waveshape can always be recovered. If the fundamental frequency is known to lie within a range not spanning any multiple of half the sampling rate, then the temporal scaling for the reconstructed waveform can be determined uniquely, as well. Procedures have also been proposed for reducing time-scale ambiguity when the latter condition is not met. A previously presented time domain algorithm for reconstructing aliased periodic signals has been implemented and modified. A new algorithm, operating in the frequency domain, has been proposed and implemented. In the new algorithm, the signal fundamental frequency is first estimated from the discrete Fourier transform of the aliased data through an iterative procedure. This estimate is then used to sort the aliased harmonics.
