H∞-Optimal Fractional Delay Filters
Fractional delay filters are digital filters to delay discrete-time signals by a fraction of the sampling period. Since the delay is fractional, the intersample behavior of the original analog signal becomes crucial. In contrast to the conventional designs based on the Shannon sampling theorem with the bandlimiting hypothesis, the present paper proposes a new approach based on the modern sample...

متن کاملOptimal Design of Fractional Delay Filters
Fractional delay filters are those that are designed to delay the input signals by a fractional amount of the sampling time. They are widely used in digital communications, speech processing, digital modeling of musical instruments, etc. Since the delay is fractional, the intersample behavior of input signals become crucial. While the conventional design bases itself on the full band-limiting a...
متن کاملFractional Delay Digital Filters
The chapter goal is focused to introduce the concept of fractional delay filters (FDF), as well as a concise description of most of the existing design techniques. For this purpose, several illustrative examples are presented, where each design method is implemented by MATLAB programs. A fractional delay filter is a filter of digital type having as main function to delay the processed input sig...
متن کاملPerformance of fractional-delay filters using optimal offset windows
Windowing is an attractive avenue for creating asymmetric FIR impulse response sequences for use as fractional-delay elements. However, traditional (symmetric) windows are not usable, leading to a need for offsetting and purpose-optimization of the windows' defining parameters. Here it is shown that as few as three terms of such a modified raised cosine window deliver enormous improvements over...
