Realisation techniques for primitive operator infinite impulse response digital filters [PDF]

open access: yes, 1993
This paper presents realisation techniques for IIR digital filters based on the primitive operator graph synthesis method. The approach exploits the redundancy present in the filter multiplier structure when the coefficients are invariant allowing ...

Evaluation of measurement uncertainty for time-dependent quantities

open access: yesEPJ Web of Conferences, 2014
One of the main challenges in the analysis of dynamic measurements is the estimation of the timedependent value of the measurand and the corresponding propagation of uncertainties.

FIR Filter Sharpening by Frequency Masking and Pipelining-Interleaving Technique

open access: yesAdvances in Electrical and Computer Engineering, 2014
This paper focuses on the improvements of digital filters with a highly sharp transition zone on the Xilinx FPGA chips by combining a sharpening method based on the amplitude change function and frequency masking and PI (Pipelining-Interleaving ...

The Use of Almost Linear Phase IIR filters In DFT Modulated Filter Banks for Communication Systems [PDF]

open access: yes, 2016
This paper is on the use and performance of M-path polyphase Infinite Impulse Response (IIR) filters for channelisation, conventionally where Finite Impulse Response (FIR) filters are preferred.

Synthesis of optical filters using sagnac interferometer in ring resonator [PDF]

open access: yes, 2007
We propose a new synthesis method for the implementation of infinite impulse response filters, using a Sagnac interferometer within a ring resonator. This structure permits the synthesis of second-order optical functions per stage.

Design of digital filters for frequency weightings (A and C) required for risk assessments of workers exposed to noise [PDF]

open access: yes, 2015
Many workers are exposed to noise in their industrial environment. Excessive noise exposure can cause health problems and therefore it is important that the worker’s noise exposure is assessed. This may require measurement by an equipment manufacturer or

Filter-Based Fading Channel Modeling

open access: yesModelling and Simulation in Engineering, 2012
A channel simulator is an essential component in the development and accurate performance evaluation of wireless systems. A key technique for producing statistically accurate fading variates is to shape the flat spectrum of Gaussian variates using ...

Circulant and skew-circulant matrices as new normal-form realization of IIR digital filters [PDF]

open access: yes, 1988
Normal-form fixed-point state-space realization of IIR (infinite-impulse response) filters are known to be free from both overflow oscillations and roundoff limit cycles, provided magnitude truncation arithmetic is used together with two's-complement ...

Variant of the charged system search algorithm for the design of optimal linear phase finite impulse response filters

open access: yesAutomatika, 2019
Digital signal filtering is one of the prime area which is frequently used in practical applications. In the class of digital filters, the prominent filters include – filters with finite impulse response (FIR) and filters with infinite impulse response ...

IIR approximation of FIR filters via discrete-time vector fitting [PDF]

open access: yes, 2008
We present a novel technique for approximating finite-impulse-response (FIR) filters with infinite-impulse-response (IIR) structures through extending the vector fitting (VF) algorithm, used extensively for continuous-time frequency-domain rational ...
