Testing Stability of Digital Filters Using Optimization Methods with Phase Analysis

Energies, 2021
In this paper, novel methods for the evaluation of digital-filter stability are investigated. The methods are based on phase analysis of a complex function in the characteristic equation of a digital filter.

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

A Novel Approach for Polyphase Filter Bank Design Using ABC Algorithm

Elektronika ir Elektrotechnika, 2022
Polyphase filter banks (PFBs) are the most preferred multirate structures for subband coding in Digital Signal Processing (DSP) and communication. For PFB design, there are many important design parameters such as filter length and frequency selectivity.
