Acoustooptic digital filter [PDF]
Applied Optics, 1985 Digital filters have three components: (1) unit delays, (2) multipliers, and (3) adders. These components can be implemented by using (1) a Bragg cell as a tapped delay line, (2) optical multiplication using the Bragg cell transmittance, and (3) photodetectors.

Classical sampling theorems in the context of multirate and polyphase digital filter bank structures [PDF]
, 1988 The recovery of a signal from so-called generalized samples is a problem of designing appropriate linear filters called reconstruction (or synthesis) filters. This relationship is reviewed and explored. Novel theorems for the subsampling of sequences are

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 ...

A Polyphase Multipath Technique for Software-Defined Radio Transmitters [PDF]
, 2006 Transmitter circuits using large signal swings and hard-switched mixers are power-efficient, but also produce unwanted harmonics and sidebands, which are commonly removed using dedicated filters.

Polyphase networks, block digital filtering, LPTV systems, and alias-free QMF banks: a unified approach based on pseudocirculants [PDF]
, 1988 The relationship between block digital filtering and quadrature mirror filter (QMF) banks is explored. Necessary and sufficient conditions for alias cancellation in QMF banks are expressed in terms of an associated matrix, derived from the polyphase ...
