Maximally Fast Scheduling of Bit-serial Lattice Wave Digital Filters Using Three-port Adaptor Allpass Sections
نویسندگان
چکیده
In this paper we show how to achieve a maximally fast lattice wave digital filter using three-port adaptor allpass sections. Using three-port adaptors may increase the maximal sampling rate with approximately 50% compared to using second-order Richards’ allpass sections. Only bitserial arithmetics is discussed in the paper, but the same ideas can be utilized for digit-serial and bit-parallel arithmetics as well.

Implementation Aspects of Second-order LDI/LDD Allpass Filters
The computational properties of second-order lossless discrete integrator/differentiator (LDI/LDD) allpass filters are studied, where the resource requirements in bit-serial hardware implementations are given particular interest. The properties of the LDI/LDD filters are compared to the corresponding properties of second-order wave digital (WD) filters using three-port series adaptors. Two impl...

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...

متن کاملImplementation of maximally fast ladder wave digital filters using a numerically equivalent state-space representation
Ladder Wave Digital Filters is a class of IIR digital filters derived from double resistively terminated ladder networks, which gives them good stability and low sensitivity to variations in the element values. An approach to design maximally fast bit-serial ladder wave digital filters is presented based on the numerically equivalent state-space representation of the signal-flow graph. An algor...
