An Efficient Method for Narrowband FIR Filter Design
A new efficient method for implementing narrowband FlR jilters is presented. The method is based on an lnterpolated jilter (lFlR) structure and a cascade of comb and integrator (ClC) structures. The novelty ofthís technique ís that the ClC structure is used as an image suppressor in an lFlR structure. The method is useful for narrowband FlRjilter design and some design examples for lowpass and ...
متن کاملEfficient and Robust Parameter Tuning for Heuristic Algorithms
The main advantage of heuristic or metaheuristic algorithms compared to exact optimization methods is their ability in handling large-scale instances within a reasonable time, albeit at the expense of losing a guarantee for achieving the optimal solution. Therefore, metaheuristic techniques are appropriate choices for solving NP-hard problems to near optimality. Since the parameters of heuristi...
متن کاملHigh-Selectivity Filter Banks for Spectral Analysis of Music Signals
This paper approaches, under a unified framework, several algorithms for the spectral analysis of musical signals. Such algorithms include the fast Fourier transform (FFT), the fast filter bank (FFB), the constant-Q transform (CQT), and the bounded-Q transform (BQT), previously known from the associated literature. Two new methods are then introduced, namely, the constant-Q fast filter bank (CQ...
متن کاملEfficient Gabor filter design for texture segmentation
Gabor lters have been successfully applied to a broad range of image processing tasks. The present paper considers the design of a single lter to segment a two-texture image. A new e cient algorithm for Gaborlter design is presented, along with methods for estimating lter output statistics. The algorithm draws upon previous results that showed that the output of a Gaborltered texture is modeled...
متن کاملPlasmonic nanostructure design for efficient light coupling into solar cells.
We demonstrate that subwavelength scatterers can couple sunlight into guided modes in thin film Si and GaAs plasmonic solar cells whose back interface is coated with a corrugated metal film. Using numerical simulations, we find that incoupling of sunlight is remarkably insensitive to incident angle, and that the spectral features of the coupling efficiency originate from several different reson...
