Polyphase FIR Networks Based on Frequency Sampling for Multirate DSP Applications
It is well known that the frequency sampling approach to the design of Finite Impulse Response digital filters allows recursive implementations which are computationally efficient when most of the frequency samples are integers, powers of 2 or nulls. The design and implementation of decimation (or interpolation) filters using this approach is studied herein. Firstly, a procedure is described wh...
متن کاملA synthesis tool for the multiplierless realization of FIR-based multirate DSP systems
In this study, a synthesis tool using a novel multirate folding technique, which handles each FIR filter in a multirate DSP system as a single node, is developed. A new architecture is presented for the multiplierless realization of a fold of multirate FIR filters. This synthesizer fully exploits the redundancies (i.e. "idle" and "missing" cycles) and common terms in multirate systems without s...
متن کاملDesign and Implementation of Low Power High Speed VLSI DSP System for Multirate Polyphase Interpolator
Interpolator is an important sampling device used for Multirate filtering to provide signal processing in wireless communication system. There are many applications in which sampling rate must be changed. Recent advances in mobile computing and communication applications demand low power and high speed VLSI DSP systems. In this paper, an efficient method has been presented to implement low powe...
متن کاملOn retiming of multirate DSP algorithms
In the paper retiming of DSP algorithms exhibiting multirate behavior is treated. Using the non-ordinary marked graph model and the reachability theory, we provide a new condition for valid retiming of multirate graphs. We show that for a graph with n nodes the reachability condition can be split into the reachability condition for the topologically-equivalent unit-rate graph (all rates set to ...
متن کاملComplex Frequency Transformations for Dsp Applications
A simple idea of the frequency transformation where each delay of the original real lowpass filter transfer function is replaced by the same allpass filter allows a lot of flexibility in manipulating the original filter to fit the required specification. The simple cases of real first-order transformations and a very few second-order ones have been suggested by Constantinides in the early 1970s...
