The analysis of conditions for preservation of gain-frequency and phase-frequency characteristics optimality under analog and digital filters transformation

open access: yesРоссийский технологический журнал, 2020
Prototype filters have wide usage for the design of filters with required quality indexes (QI) of gain-frequency response (GFR). The designed filter is obtained from a prototype filter b means of frequency transformation, which preserves these QI.

On prefilters for digital FIR filter design [PDF]

open access: yes, 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 new approach to the realization of low-sensitivity IIR digital filters [PDF]

open access: yes, 1986
A new implementation of an IIR digital filter transfer function is presented that is structurally passive and, hence, has extremely low pass-band sensitivity. The structure is based on a simple parallel interconnection of two all-pass sections, with each
