FIR Digital Filter Design

2018
In Chap. 5, the design of IIR filters was considered. In many digital signal processing applications, FIR filters are preferred to IIR filters because of the following advantages of FIR filters.

On the design of recursive lowpass digital filters

ICASSP '79. IEEE International Conference on Acoustics, Speech, and Signal Processing, 1980
The magnitude-squared characteristic of an ideal lowpass filter is approximated, over the finite interval [-1,1], by the ratio Φ(x)/Φ(x)+P(x) of two n-th-degree polynomials. The polynomials Φ(x) and P(x) are chosen such that the ratios P(x)/ Φ(x) and Φ(x)/P(x) approximate, in a Chebyshev sense, the zero function over the passband [x p ,1] and the ...

Digital filters design by simulated annealing

IEEE Transactions on Circuits and Systems, 1989
Presents preliminary results on the application of the simulated annealing (SA) algorithm to solve the general discrete coefficients filter design problem. The main characteristics of the approach taken with respect to optimal algorithms is that no particular assumptions are made on the filter structure or the cost function.

Issues in the design of digital Nyquist filters

International Conference on Acoustics, Speech, and Signal Processing, 2003
The authors examine the tradeoffs involved in the design of digital raised-cosine Nyquist filters for application in digital computer simulation or for incorporation in all-digital data modems. Both floating-point arithmetics (for simulation applications) and finite-precision arithmetics are considered.

Design of bilinear digital ladder filters

Proceedings of ISCAS'95 - International Symposium on Circuits and Systems, 2002
Methods for designing bilinear switched-capacitor (SC) ladder filters are well known. However, they cannot be directly extended to digital filters because of the delay-free loops allowed in SC filters. In the present paper, design methods for low-sensitive bilinearly transformed voltage-current ladder filters are developed.

Design and Implementation of Digital Tomographic Filters

IEEE Transactions on Medical Imaging, 1983
A technique is proposed which allows the selective filtering of conventional radiographs in order to obtain depth-dependent information by utilizing the depth-dependent information contained therein. This technique, referred to as tomographic filtering or tomographic filtration process (TFP), takes advantage of the finite size of the X-ray source, so ...

Array based design of digital filters

IEEE Transactions on Acoustics, Speech, and Signal Processing, 1990
It is noted that signal processing designs for real-time large-scale systems are increasingly confronted with two conflicting objectives. The traditional objective of optimal design in low signal-to-noise ratio environments is confronted with the need for simplicity in implementation and speed of computation.

Generalized digital Butterworth filter design

1996 IEEE International Conference on Acoustics, Speech, and Signal Processing Conference Proceedings, 1998
This paper presents a formula-based method for the design of IIR filters having more zeros than (nontrivial) poles. The filters are designed so that their square magnitude frequency responses are maximally-flat at /spl omega/=0 and at /spl omega/=/spl pi/ and are thereby generalizations of classical digital Butterworth filters.
