An equiripple FIR filter is designed and then converted to an IIR equivalent. The original linear-phase characteristic is preserved across the passband of the IIR filter, exemplifying the concept of a stable IIR filter with "almost linear phase".

FIR filters with generalized linear phase can have even or odd order and even or odd symmetry, resulting in four different types. Constraints on the frequency response and zero locations are presented for each filter type.

Slifer is available at http://www.dspcreations.com/slifer1.html
A two-band linear-phase FIR filter is designed and modified so that it has two distinct group delay plateaus. Finally the FIR serves as the prototype for a conversion to IIR realization.

Sketch-a-Filt is available at http://www.dspcreations.com/sketch1.html
Here the tradeoffs among band ripples and transition widths in digital filter designs are treated. Three styles of FIR design (Frequency-Sampling, Impulse-Invariant, and Remez), are examined since these furnish extremes for contrasting quality metrics.

Here a maximum-phase digital filter (notoriously resistant to inverse filtering) is invoked. Satisfactory spectral amplitude compensation is achieved by an FIR filter.

A minimum-phase lowpass FIR filter with very low passband and stopband ripples is first presented. Then it is shown that the transition width for the gain can be substantially reduced by liberating the ripple constraints in one or both bands.

Filter design is the process of designing a signal processing filter that satisfies a set of requirements, some of which are contradictory. The purpose is to find a realization of the filter that meets each of the requirements to a sufficient degree to make it useful.
The filter design process can be described as an optimization problem where each requirement contributes to an error function which should be minimized. Certain parts of the design process can be automated, but normally an experienced electrical engineer is needed to get a good result.

This paper proposes an efficient constantmultiplier architecture based on vertical-horizontal binary common
sub-expression elimination (VHBCSE) algorithm for designing a
reconfigurable finite impulse response (FIR) filter whose coefficients can dynamically change in real time. To design an efficient
reconfigurable FIR filter, according to the proposed VHBCSE
algorithm, 2-bit binary common sub-expression elimination
(BCSE) algorithm has been applied vertically across adjacent
coefficients on the 2-D space of the coefficient matrix initially,
followed by applying variable-bit BCSE algorithm horizontally
within each coefficient. This technique is capable of reducing
the average probability of use or the switching activity of the
multiplier block adders by 6.2% and 19.6% as compared to that
of two existing 2-bit and 3-bit BCSE algorithms respectively.
ASIC implementation results of FIR filters using this multiplier
show that the proposed VHBCSE algorithm is also successful in
reducing the average power consumption by 32% and 52% along
with an improvement in the area power product (APP) by 25%
and 66% comparedto those of the 2-bit and 3-bit BCSE algorithms respectively. As regardsthe implementation of FIR filter,
improvements of 13% and 28% in area delay product (ADP) and
76.1% and 77.8% in power delay product (PDP) for the proposed
VHBCSE algorithm have been achieved over those of the earlier
multiple constant multiplication (MCM) algorithms, viz. faithfully
roundedtruncated multiple constant multiplication/accumulation
(MCMAT) and multi-root binary partition graph (MBPG) respectively. Efficiency shown by the results of comparing the FPGA and
ASIC implementations of the reconfigurable FIR filter designed
using VHBCSE algorithm based constant multiplier establishes
the suitability of the proposed algorithm for efficient fixed point
reconfigurable FIR filter synthesis.
