An Analytical Design Procedure For Bireciprocal Lattice Wave Digital Filters With Approximate Linear Phase
نویسنده
چکیده
A simple analytic design procedure for bireciprocal lattice wave digital filters (bireciprocal LWDFs) is presented with approximate linear phase. The design is started by replacing the odd order all-pass filter branch in the bireciprocal LWDF with a pure delay, leaving the other branch as an all-pass even function of z . Analytic design procedure is then formulated. Several design examples using such procedure are given for verifications.

Design of Bireciprocal Linear- Phase Lattice Wave Digital Filters
In this paper we describe an algorithm for design of bireciprocal linearphase lattice wave digital filters. The designed filters are characterized by the property of having a maximal number of attenuation zeros for a given filter order. Some design examples using this algorithm are also given.
متن کاملWave Digital Filter Structures for High-Speed Narrow-Band and Wide-Band Filtering
Wave digital filter (WDF) structures for high-speed narrow-band and wide-band filtering are introduced. The narrow-band filter is composed of a periodic model filter and one or several, possibly periodic, masking filters in cascade. Lattice and bireciprocal lattice WDF filters are used for the model and masking filters, respectively. The wide-band filter consists of a narrow-band filter in para...

In this paper, Bireciprocal Lattice Wave Digital Filters (BLWDFs) are utilized in an approximate linear phase design of 9 th order IIR wavelet filter banks (FBs). Each of the two branches in the structure of the BLWDF realizes an Allpass filter. The low-coefficient sensitivity, excellent dynamic range and good stability properties of such filters allow their realization with short coefficient w...
متن کاملBireciprocal lattice wave digital filters with almost linear phase response
In this paper two methods for designing almost linear phase wave digital filters are compared. First of them is based on designing a minimum phase filter and equalizing its phase response by some all-pass equalizer. The, second one utilizes previously published method of designing'almost linear phase filters without the equalizer. Several improvements to bo? approaches are introduced and a comp...

In this paper we propose an arithmetic transformation of firstorder allpass lattice wave digital filter sections implemented with bit-parallel, carry-save arithmetic which increases the maximum sample rate. Such filter sections are the critical component of bireciprocal lattice wave digital filters which are efficient filter structures for sample rate conversion with factors of two. The propose...
