Realisations of Finite-Sample Frequency-Selective Filters
A filtered data sequence can be obtained by multiplying the Fourier ordinates of the data by the ordinates of the frequency response of the filter and by applying the inverse Fourier transform to carry the product back to the time domain. Using this technique, it is possible, within the constraints of a finite sample, to design an ideal frequency-selective filter that will preserve all elements...
متن کاملImproved frequency selective filters
This paper is concerned with the design and implementation of frequencyselective recursive filters in which the filtered output is incorporated on the input side, at various lags, via a series of feedback terms. Such devices are commonly described as infinite impulse response (IIR) filters. Filters that are devoid of feedback are apt to be described as finite impulse response (FIR) filters. Rel...
متن کاملRobust Frequency - Selective Filtering usingWeighted Myriad Filters
Weighted Myriad Smoothers have recently been proposed as a class of nonlinear l-ters for robust non-Gaussian signal processing in impulsive noise environments. However , weighted myriad smoothers are severely limited, since their weights are restricted to be non-negative. This constraint makes them unusable in bandpass or highpass ltering applications which require negative lter weights. Furthe...
متن کاملYangian realisations from finite W-algebras
We construct an algebra homomorphism between the Yangian Y (sl(n)) and the finite W-algebras W(sl(np), n.sl(p)) for any p. We show how this result can be applied to determine properties of the finite dimensional representations of such W-algebras. hep-th/9803243 CERN-TH/98-104 LAPTH-672/98 March 1998 [email protected] On leave of absence from LAPTH.

متن کاملDesign of Low-Cost Frequency-Selective Analog and Digital Filters
Classical filter design is typically based on the assumption that the cost is proportional to the filter order. Here we revisit this assumption and show that is may be advantageous to instead use filter structures that have low sensitivity to element errors. We first discuss the mechanism behind the low sensitivity of doubly resistively terminated lossless networks and estimated of the passband...
