The purpose of this study is to test the Brenner hypothesis using a Bayesian vector autoregressive approach, to compute impulse response function and to conclude if evidence of the hypothesis exist in Canadian data.

Digital filters are vastly utilized in the area of communication. A perfect digital filter efficiency is significant and hence to design a finite impulse response (FIR) favorable all wanted situations necessary. In this paper, new proposed FIR designed, fineness submitted tested terms BER then matched with another window, namely Hamming, Hanning, Blackman. The procedure done MATLAB software. It...

In traditional warped FIR and IIR filters, the frequency-warping profile is adjusted by a single free parameter, leading to a less flexible allocation of frequency resolution. As an example, it is not possible to achieve a truly logarithmic frequency resolution, which would be often desired in audio applications. In this paper a new approach is presented for warped IIR filter design where the f...

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...

The aim of this work is to study the validity of impulse approximations to model discrete systems using filter-based identification methods. Even when impulse inputs possess an inherent error due to the physical impossibility of generation of ideal impulses, they are of particular practical interest when treating discrete-time systems where the analytical resolution becomes very complex or even...

In this paper, we study the linear zero-forcing equalizability of a communication channel. Necessary and suucient conditions are given in terms of zeros of the transfer function. Detailed procedures of equalizer design for minimum sensitivity with respect to modeling errors and white noise are also presented. It is found that the worst-case eeect of channel mismatch on the performance may be mo...

A new method for designing IIR digital filters with linear phase in the passband is proposed. This method is based on frequency weighted least-square error optimization using the BFGS method [15]. The gradient of the cost function with respect to the design parameters, required for the implementation of the BFGS method, is derived. The proposed method is started by obtaining an initial IIR filt...
