The stability of a procedure for the recovery of lost samples in band-limited signals
نویسنده
چکیده
In this paper we study the eigenvalues of a matrix S which arises in the recovery of lost samples from oversampled band-limited signals. Emphasis is placed on the variation of the eigenvalues as a function of the distribution of the missing samples and as a function of the oversampling parameter. We present a number of results which help to understand the numerical difficulties that may occur in this class of problems, and ways to circumvent them. Keywords— Sampling, lost samples, interpolation, eigenvalues, stability, ill-posed problems, band-limited signals.

متن کاملA Study on Neodymium Recovery from Aqueous Solutions for Designing a New Generation of Sandwich Liquid Membrane
Liquid Membrane (LM) based processes, as Supported Liquid Membranes (SLMs), have been proposed, for over 30 years, as effective methods for the selective separation of inorganic/organic species from different water streams. The industrial use of SLMs has been limited mainly by their insufcient stability. To investigate on the main cause of system destabilization and the o...
متن کاملHealth Monitoring for Composite under Low-Cycle Cyclic Loading, Considering Effects of Acoustic Emission Sensor Type
Composites have been widely used in the aerospace industry. Due to the requirement of a high safety for such structures, they could be considered for health monitoring. The acoustic emission approach is one of most effective methods for identifying damages in composites. In this article, standard specimens were made from carbon fibers and the epoxy resin, with the [03/902/...
متن کاملNonuniform sampling, image recovery from sparse data and the discrete sampling theorem.
In many applications, sampled data are collected in irregular fashion or are partly lost or unavailable. In these cases, it is necessary to convert irregularly sampled signals to regularly sampled ones or to restore missing data. We address this problem in the framework of a discrete sampling theorem for band-limited discrete signals that have a limited number of nonzero transform coefficients ...
متن کاملA Compact UWB Bandpass Filter with High Selectivity and Dual Notched-Band
A novel compact-sized ultra-wideband (UWB) bandpass filter (BPF) is proposed in this paper. The proposed BPF is highly selective and is able to eliminate WLAN signals from 5.15-5.35 GHz, and downlink of X-band satellite communication signals from 7.25-7.75 GHz. Generally, a multiple-mode resonator (MMR), comprised of a U-shaped line, with two high impedance stubs connected to it, and one steppe...
