Digital filters find wide variety of applications in modern digital signal processing systems [1, 2]. As a result of the recent progress in such systems, there is an ever growing demand for sharp transition band digital filters. These narrow transition bandwidth digital filters are usually designed by using the frequency response masking (FRM) approach [3]. The computational efficiency of the F...

In this papec we propose a new subsequence matching method, DualMatch, which exploits duality in constructing windows and significantly improves performance. Qual Match divides data sequences into disjoint windows and the query sequence into sliding windows, and thus, is a dual approach of the one by Faloutsos et al. (FRM in short), which divides data sequences into sliding windows and the quer...

The frequency-response masking (FRM) technique was introduced as a means of generating linear-phase FIR filters with narrow transition band and low arithmetic complexity. This paper proposes an approach for synthesizingmodulatedmaximally decimated FIR filter banks (FBs) utilizing the FRM technique. A new tailored class of FRM filters is introduced and used for synthesizing nonlinear-phase analy...

— It is well known that frequency response masking (FRM) FIR digital filters can be designed to exhibit very sharp-transition bands at the cost of slightly larger filter lengths as compared to the conventional FIR digital filters. The FRM FIR digital filters permit efficient hardware implementations due to an inherently large number of zero-valued multiplier coefficients in their transfer funct...

A typical household has a home mortgage as its most significant financial contract. The form of this contract is correspondingly important. This paper studies the choice between a fixed-rate (FRM) and an adjustable-rate (ARM) mortgage. In an environment with uncertain inflation, a nominal FRM has risky real capital value whereas an ARM has a stable real capital value. However an ARM can increas...

This paper studies the design of frequency response masking (FRM) filters with infinite duration impulse response (IIR) model and masking sub-filters. They are useful in realizing sharp cutoff digital filters with low passband delays. The designs of the model and masking filters are carried out by means of semidefinite programming (SDP) and model order reduction. Design results show that low co...

The construction of the new German high flux neutron source FRM-II is finished and FRM-II is waiting for its licence to start nuclear operation. With the beginning of the routine operation 22 instruments will be in action, including 5 irradiation facilities and 17 beam tube instruments, most of them use neutron scattering techniques. Additional instruments are under construction. Some of these ...

An efficient technique for drastically reducing the number of multipliers and adders in narrow-transition band linear-phase finite-impulse response filters is to use one-stage or multistage frequency-response masking (FRM) approaches as originally introduced by Lim. It has been observed recently that for the onestage FRM approach the filter complexity can be considerably reduced by iteratively ...
