Implementation of a Combined High-speed Interpolation and Decimation Wave Digital Filter

چکیده
In this paper we discuss the design and implementation of a novel class of high-speed wave digital filter structures for interpolation and decimation. Four different structures were compared with respect to chiparea, power consumption and speed. The best of these structures was combined into an interpolation and decimation filter and have been implemented using redundant arithmetic and standard-cells.

High-speed recursive filter structures for interpolation and decimation with factors of two, and quadrature mirror filter (QMF) banks with perfect magnitude reconstruction, are proposed. The structures are composed of identical all-pass subfilters that are interconnected via extra multipliers. For the case of interpolation and decimation filters, the overall transfer function corresponds in the...

ABSTRACT In this paper we discuss the design and implementation of a highspeed FIR filter for both interpolation and decimation of the sample frequency. Several FIR filter structures are compared and various schemes for simplifying the implementation of the multiplications are evaluated. Carry-save adders with carryoverflow correction are used in the implementation. The results in terms of chip...

In DSP applications, Low pass filters are used for decimation and for interpolation. While decimating, low pass filters are used to reduce the bandwidth of a signal before reducing the sampling rate. This is done to minimize aliasing effect produced due to the overlapping of replicas of original spectrum. In this paper, Area Efficient and Cost Effective Techniques for design polyphase decimatio...

متن کاملHigh-speed Recursive Filter Structures for Interpolation and Decimation with Factors of Two
Abs t rac t – In this paper we propose high-speed recursive filter structures for interpolation and decimation with factors of two. The structures are composed of identical allpass subfilters and mult ip l iers that interconnect these subfilters. In the simplest case, the overall transfer function corresponds to several half-band IIR filters in cascade. It can also be designed to have a smaller...
