Digital Filters with Adaptive Length for Real-Time Applications
This paper explores the use of imprecise computing to develop digital filters with adaptive length in order to meet real-time constraints. A large-order filter typically provides better filtering but takes longer to compute than a low order filter. An adaptive length filter can provide a resource manager with alternatives that can be used if resources become scarce. This paper discusses the use...
متن کاملAdaptive design of digital filters
In this paper, we present a novel technique for the design of FIR and IIR digital filters. The design approach begins with the specification of a discrete set of arbitrary magnitude and phase characteristics which describe a desired filter response. These frequency domain characteristics are used to create an ideal 'pseudo-filter' whose impulse response is unknown and possibly non-causal, but w...
متن کاملAdaptive Time-Stepping and Computational Stability
We investigate the effects of adaptive time-stepping and other algorithmic strategies on the computational stability of ODE codes. We show that carefully designed adaptive algorithms have a most significant impact on computational stability and reliability. A series of computational experiments with the standard implementation of Dassl and a modified version, including stepsize control based on...
متن کاملAdaptive Time Stepping in Real-Time Motion Planning
Replanning is a powerful mechanism for controlling robot motion under hard constraints and unpredictable disturbances, but it involves an inherent tradeoff between the planner’s power (e.g., a planning horizon or time cutoff) and its responsiveness to disturbances. We present a real-time replanning technique that uses adaptive time stepping to learn the amount of time needed for a sample-based ...
متن کاملDemystifying the Digital Adaptive Filters Conducts in Acoustic Echo Cancellation
A digital sound system resembles the wireless network link transmission system. A wireless network link is affected by several disturbing factors: fading, attenuation, non-linear distortion and noise. These factors are also unavoidable in acoustic echo cancellation. A few number of digital adaptive filter algorithms are approached to detect and cancel the noise in a system. Among these algorith...
