A Unified Approach to the Theory of Sampling Systems*
This paper presents a new method for the analysis of sampling (or sampled-data) systems. Unlike methods currently in use, it is not necessary to assume that the sampling operations are synchronous, performed at constant rate, and representable by means of an impulse modulator. Several different types of sampling operations are considered in detail, with the analysis proceeding similarly in each...
متن کاملSampling of Multiple Variables Based on Partially Ordered Set Theory
We introduce a new method for ranked set sampling with multiple criteria. The method relaxes the restriction of selecting just one individual variable from each ranked set. Under the new method for ranking, units are ranked in sets based on linear extensions in partially order set theory with considering all variables simultaneously. Results willbe evaluated by a relatively extensive simulation...
متن کاملSampling theory and practice
Sampling is a scientist’s way of collecting information, and the majority of sampling is undertaken to answer specific questions. This was not always the case. Sampling as we know it was first done in a haphazard manner and bore little relation to what we would call sampling today. The first samples taken were basically a by-product of the desire of natural historians to collect information abo...
متن کاملMultiplexing and Sampling Theory
Sampled-Data Systems An ideal data acquisition system uses a single ADC for each measurement channel. In this way, all data are captured in parallel and events in each channel can be compared in real time. But using a multiplexer, Figure 3.01, that switches among the inputs of multiple channels and drives a single ADC can substantially reduce the cost of a system. This approach is used in so-ca...
متن کاملSampling Theory and Wavelets
We introduce the theory of frames and develop wavelet theory as a natural extension of the Classical Sampling Theorem. This material serves as background for our applications to periodicity detection, noise reduction, and multidimensional irregular sampling.
