چکیده

Chebyshev functions, which are equiripple in a certain domain, are used to generate equiripple halfband lowpass frequency responses. Inverse Fourier transformation is then used to obtain explicit formulas for the corresponding impulse responses. The halfband lowpass FIR digital filters designed in this way are quasi-equiripple, having performances very close to those of true equiripple filters, and are comparatively much simpler to design.

Quasi-equiripple approximation of minimum phase FIR filters by updating desired response

The authors present a new numerical method for the Chebyshev approximation of minimum phase FIR digital filters. This method is based on solving a least squares (LS) problem iteratively. At each iteration, the desired response is transformed so as to have an equiripple magnitude error. This method makes it possible to design minimum phase FIR filters whose magnitude error is quasi-equiripple. U...

On Prefilters for Digital FIR Filter Design

Absrruct -A new family of digital prefilter structures is introduced, based on the Dolph-Chebyshev function. These prefilters can be combined with appropriately designed “equalizer” filters based on equiripple methods, leading to efficient FIR digital filter designs. Design examples are included, demonstrating the simplicity of the resulting designs, as compared to conventional equiripple designs.

New designs of low/high‐pass and mid‐pass/stop FIR digital filters

New designs of highly e8cient low=highand mid-pass=stop (centre-symmetric band-pass=stop) FIR non-recursive digital 0lters are presented. The designs are based on the modulation property of DFT, applied to the already presented MAXFLAT halfband low-pass 0lters. The presented 0lters have explicit formulas for their tap-coe8cients, and therefore are very easy to design. They have highly smooth fr...

Optimal Design of Linear-Phase FIR Digital Filters with Very Flat Passbands and Equiripple Stopbands

Ahs~aet-A new technique is presented for the design of digital FIR filters, with a prescribed degree of flatness in the passband, and a prescribed (equiripple) attenuation in the stopband. The design is based entirely on an appropriate use of the well-known Rem&-exchange algorithm for the design of weighted Chebyshev FIR filters. The extreme versatility of this algorithm is combined with certai...

A weighted least square algorithm for low-delay FIR filters with piecewise variable stopbands

Variable digital filters are useful for various signal processing and communication applications where the frequency characteristics, such as fractional delays and cutoff frequencies, can be varied. In this paper, we propose a design method of variable FIR digital filters with an approximate linear phase characteristic in the passband. The proposed variable FIR filters have some large attenuati...
