Design of an equiripple FIR notch filter using a multiple exchange algorithm
نویسندگان
چکیده
This paper presents a multiple exchange algorithm for designing linear phase equiripple FIR notch "lters. The algorithm is "rst discussed for designing a single notch "lter. Compared with conventional linear programming methods, the design speed can be improved signi"cantly. Then, two modi"ed algorithms are developed to reduce the ripple in the low-frequency passband because the energy of biomedical ECG signals is usually occupied in the low-frequency band. Next, we extend the proposed algorithm to design an equiripple multiple-notch "lter. Finally, several design examples are presented to demonstrate its e!ectiveness. ( 1999 Elsevier Science B.V.

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...
متن کاملDesign of Equiripple FIR Filters With Constraint Using a Multiple Exchange Algorithm
We propose a method of designing equiripple linear-phase FIR filters with linear constraint by carrying out the Remèz exchange algorithm. A novel technique is derived to convert a linearly constrained problem into an equivalent unconstrained one. We proposed a technique to modify the original desired frequency response so that the original linear constraint can be reduced to a simpler one (the ...
متن کاملDesign of Equiripple Minimum Phase FIR Filters with Ripple Ratio Control
In this paper, we present a numerical method for the equiripple approximation of minimum phase FIR digital filters. Many methods have been proposed for the design of such filters. Many of them first design a linear phase filter whose length is twice as long, and then factorize the filter to obtain the minimum phase. Although these methods theoretically guarantee its optimality, it is difficult ...

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...
