Low Cost Nonrecursive Digital Filter Structures
This paper presents a novel method of hardware reduced fast FIR filter structure for parallel data processing.In general, arithmetic operation modules such as adder and multiplier modules, consume much power, energy, and circuit area. The power consumed by the adder structure is also very significant while designing a low power filter. The proposed low power multipliers and low power adders are...
متن کاملFIR filter structures having low sensitivity and roundoff noise
Absrraer—A class of structures for FIR fiiters is presented, which exhibits reduced coefficient sensitivity and superior roundoff noise properties as compared to the direct form realization. It is shown that using fixed-point arithmetic, these structures achieve the same accuracy and about the, same roundoff noise as those obtained in the floatingpoint implementation. The optimum structure to a...
متن کاملLow Sensitivity, Low Power BP Active Filter Structures with Biquads using Impedance Tapering
This paper presents the realization of narrow high-order band-pass (BP) active resistance-capacitance (RC) filters. It was shown that such filters have large sensitivities to component tolerances, and if they were built using structures with multiple feedbacks, theirs sensitivities are substantially decreased. Furthermore, it was demonstrated that sensitivities of inner 2-order blocks (“biquads...
متن کاملFloorplan-aware Low-complexity Digital Filter Synthesis
In this paper, we propose a floorplan-aware complexity reduction methodology for digital filters. The proposed scheme integrates high-level synthesis and floorplan to obtain improvement in both computational complexity and interconnect delay. Physical information of floorplan is incorporated into architecture synthesis. By considering interconnects while synthesizing reduced-complexity filters,...
متن کاملLow latency IIR digital filter design by using metaheuristic optimization algorithms
Filters are particularly important class of LTI systems. Digital filters have great impact on modern signal processing due to their programmability, reusability, and capacity to reduce noise to a satisfactory level. From the past few decades, IIR digital filter design is an important research field. Design of an IIR digital filter with desired specifications leads to a no convex optimization pr...
