On fast FIR filters implemented as tail-canceling IIR filters
We have developed an algorithm based on synthetic division for deriving the transfer function which cancels the tail of a given arbitrary rational (IIR) transfer function after a desired number of time steps. Our method applies to transfer functions with repeated poles, whereas previous methods of tail-subtraction cannot [1]. We use a parallel state-variable technique with periodic refreshing t...
متن کاملEfficient Complex Continuous-Time IIR Filter Design via Generalized Vector Fitting
We present a novel model identification technique for designing complex infinite-impulseresponse (IIR) continuous-time filters through generalizing the Vector Fitting (VF) algorithm, which is extensively used for continuous-time frequencydomain rational approximation to symmetric functions, to asymmetrical cases. VF involves a twostep pole refinement process based on a linear leastsquares solve...
متن کاملDesign of Discrete Coefficient FIR and IIR Digital Filters with Prefilter-Equalizer Structure Using Linear Programming
Optimal methods for designing multiplierless finite-impulse response (FIR) and infinite-impulse response (IIR) filters with cascaded prefilter-equalizer structures are proposed. Assuming that an FIR filter consists of a cyclotomic polynomial (CP) prefilter and an interpolated second order polynomial (ISOP) equalizer, in the proposed method, the prefilter and equalizer are simultaneously designe...
متن کاملA continuous approximation fitting to the discrete distributions using ODE
The probability density functions fitting to the discrete probability functions has always been needed, and very important. This paper is fitting the continuous curves which are probability density functions to the binomial probability functions, negative binomial geometrics, poisson and hypergeometric. The main key in these fittings is the use of the derivative concept and common differential ...
متن کاملH2 / H∞ FIR Filters for Discrete-time State Space Models
In this paper a new type of filter, called the H2 / H∞ FIR filter, is proposed for discretetime state space signal models. The proposed filter requires linearity, unbiased property, FIR structure, and independence of the initial state information in addition to the performance criteria in both H2 and H∞ sense. It is shown that H2, H∞, and H2 / H∞ FIR filter design problems can be converted into...
