We characterize the wavelet multipliers, as well as the scaling function multipliers and low pass filter multipliers.


For compactly supported gm, n (FIR filter banks) we prove an exponential rate of convergence and derive explicit expressions for the involved constants.


This, in turn, is used for designing local orthogonal bases obtained by unitary transformations of a single prototype filter.


This in turn, is used for designing local orthogonal bases obtained by unitary transformations of a single prototype filter.


The measure for uncertainty is a product of two factors evaluating the frequency selectivity in comparison with the ideal filter and the effective length of the filter in the digital domain, respectively.


The uncertainty product of such minimizing filters approaches the unrestricted infimum as the filter length increases.


In particular, the concept of a fuzzy subgroup with thresholds is extended to the concept of an interval valued fuzzy filter with thresholds in BLalgebras.


In view of reasonable explanation of intermittent subharmonics and chaos that can be gained from coupling filter between circuits, this paper discusses a method that maps time bifurcation with parameter bifurcation.


On the basis of direct sequence spread system (DSSS), frequency shift filter is added into the receiver of the communication system.


Although the structure of frequency shift filter is more complicated than the timedomain filter, it uses both time correlations and frequency spectrum correlations so it can achieve better performances on separating the overlapping signals.


After the analysis of cyclostationary characteristic and frequency spectrum correlation, the structure of the frequency shift filter can be gained.


Digital controller for hybrid filter in HVDC based on approximate inverse system


A tappedinductor is used to replace the normal output filter inductor, so that the circulating current in the zerostate can be reset to zero.


We conclude that the filtercapacitance of the rectifier can be designed.


A low pass filter was designed to filter the carry waves of the sweeping source.


The study also shows that higher orders are almost totally suppressed by MgF2 filter when the wavelength ranges between 115140 nm.


The design of the gainscheduled H2/H∞ filter for polytopic discretetime systems is investigated.


Based on the new performance criterion, a sufficient condition for the existence of the gainscheduled H2/H∞ filter is derived.


Furthermore, the filter design problem is converted into a convex optimization problem with linear matrix inequality (LMI) constraints.


Methods of computer vision, image processing and wavelet analysis technology were used to compress, filter, segment, abate noise and capture the outline of the picture.
