On maximally-flat linear-phase FIR filters [PDF]
, 1984 An implementation for maximally-flat FIR filters is proposed that requires a much smaller number of multiplications than a direct form structure. The values of the multiplier coefficients in the implementation are conveniently small, and do not span a ...

On prefilters for digital FIR filter design [PDF]
, 1985 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 ...

Theory and design of uniform DFT, parallel, quadrature mirror filter banks [PDF]
, 1986 In this paper, the theory of uniform DFT, parallel, quadrature mirror filter (QMF) banks is developed. The QMF equations, i.e., equations that need to be satisfied for exact reconstruction of the input signal, are derived.

Distributed Autoregressive Moving Average Graph Filters
, 2015 We introduce the concept of autoregressive moving average (ARMA) filters on a graph and show how they can be implemented in a distributed fashion.

A new general expression for 2-channel FIR paraunitary filterbanks [PDF]
, 2008 This paper provides a new explicit expression for all real FIR paraunitary filters. From this we derive a new procedure for the design of the L components of any 2-channel FIR orthogonal L-tap filter.

On the eigenfilter design method and its applications: a tutorial [PDF]
, 2003 The eigenfilter method for digital filter design involves the computation of filter coefficients as the eigenvector of an appropriate Hermitian matrix.

On parameter filtering in continuous subword-unit-based speech recognition [PDF]
, 1996 Simple IIR or FIR filters have been widely used in isolated or connected word recognition tasks to filter the time sequence of speech spectral parameters, since, despite their simplicity, they significantly improve recognition performance. Those filters,

Optimum low cost two channel IIR orthonormal filter bank [PDF]
, 1997 In this paper, we statistically optimize a well known class of IIR two channel orthonormal filter banks parameterized by a single coefficient when subband quantizers are present.

Non-uniform wordlength delay lines for FIR filters [PDF]
, 2009 When FIR filters are designed floating point arithmetic is generally used. However when implemented on hardware such as ASICs, fixed point arithmetic must be used to minimise cost and power requirements.
