Sampling Discrete-time Piecewise Bandlimited Signals
We consider sampling discrete-time periodic signals which are piecewise bandlimited, that is, a signal that is the sum of a bandlimited signal with a piecewise polynomial signal containing a finite number of transitions. These signals are not bandlimited and thus the Shannon sampling theorem for bandlimited signals can not be applied. In this paper, we derive sampling and reconstruction schemes...
متن کاملNovel Sampling and Reconstruction Method for Non-Bandlimited Impulse Signals
⎯To sample non-bandlimited impulse signals, an extremely high-sampling rate analog-todigital converters (ADC) is required. Such an ADC is very difficult to be implemented with present semiconductor technology. In this paper, a novel sampling and reconstruction method for impulse signals is proposed. The required sampling rate of the proposed method is close to the signal innovation rate, which ...
متن کاملReconstruction of irregularly sampled discrete-time bandlimited signals with unknown sampling locations
The purpose of this paper is to develop methods that can reconstruct a bandlimited discrete-time signal from an irregular set of samples at unknown locations. We define a solution to the problem using first a geometric and then an algebraic point of view. We find the locations of the irregular set of samples by treating the problem as a combinatorial optimization problem. We employ an exhaustiv...
متن کاملTime encoding and perfect recovery of bandlimited signals
A Time Encoding Machine is a real-time asynchronous mechanism for encoding amplitude information into a time sequence. We investigate the operating characteristics of a machine consisting of a feedback loop containing an adder, a linear filter and a Schmmitt trigger. We show how to recover the amplitude information of a bandlimited signal from the time sequence loss-free.
متن کاملSampling and Reconstruction of Bandlimited BMO-Functions
Functions of bounded mean oscillation (BMO) play an important role in complex function theory and harmonic analysis. In this paper a sampling theorem for bandlimited BMO-functions is derived for sampling points that are the zero sequence of some sine-type function. The class of sinetype functions is large and, in particular, contains the sine function, which corresponds to the special case of e...
