Implementation of Narrow-band Lattice Wave Digital Filters

چکیده
Recently, a filter structure for narrow-band filtering based on lattice wave digital filters was introduced. The structure has increased parallelism over the corresponding direct realization. In this paper, hardware implementation of the filter structure is discussed. The suggested approach uses bit-serial processing elements that are scheduled so that a maximally fast implementation is achieved. An example is given where our implementation approach increases the sample frequency by a factor of 4 compared to a direct realization.

Wave 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...
متن کاملA new approach to the realization of low-sensitivity IIR digital filters
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 section implemented in a structurally lossless manner. The structure shares a number of properties in common with wave lattice digital filters...
متن کاملNarrow-band and wide-band high-speed recursive digital filters using single filter frequency masking techniques
In this paper the design of single filter frequency masking recursive filters is discussed. We briefly review the previously proposed lowpass narrow-band filters and propose a design method for highpass narrow-band filters. Wide-band filters are also discussed. The proposed approach uses several identical filters, except for periodicity, which are mapped to a single hardware structure using fol...

ABSTRACT In this paper a novel structure for frequency masking based on a single filter is introduced. By using the proposed frequency masking approach the maximal sample frequency for narrow-band recursive digital filters is increased. This increase in sample frequency can be utilized either for faster filters or for lower power consumption by trading excess speed for low power. As the subfilt...
متن کاملImplementation of Bit-parallel Lattice Wave Digital Filters with Increased Maximal Sample Rate
In this paper arithmetic transformations for increased maximal sample rate of bit-parallel lattice wave digital filters implemented with carry-save arithmetic are proposed. The purpose is to increase the throughput in order to allow a reduction of the power consumption through supply voltage scaling. A lattice wave digital filter can be composed of firstand secondorder allpass sections which ar...
