چکیده
This paper describes a modiication of a technique proposed by Vaidyanathan for the design of lters having at passbands and equiripple stopbands. The modiication ensures that the passband is monotonic and does so without the use of concavity constraints. Another modi-cation described in this paper adapts the method of Vaidyanathan to the design of lowpass diierentiators having a speciied degree of tangency at ! = 0.

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 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 ...
متن کاملDesign of Stable IIR Digital Filters With Equiripple Passbands and Peak-Constrained Least-Squares Stopbands
This paper describes an algorithmic development for the design of stable infinite impulse response (IIR) digital filters with equiripple passbands and peak-constrained leastsquares stopbands. Central to the development is a re-formulation of the design problem as an iterative quadratic programming problem where the stability and equiripple passbands and peakconstrained requirements are met by i...
متن کاملA 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...
