Universal maximally flat lowpass FIR systems
The family of FIR digital filters with maximally flat magnitude and group delay response is considered. The filters were proposed by Baher, who furnished them with an analytic procedure for derivation of their transfer function. The contributions of this paper are the following. A simplified formula is presented for the transfer function of the filters. The equivalence of the novel formula with...
متن کاملMaximally positive polynomial systems supported on circuits
A real polynomial system with support W ⊂ Z is called maximally positive if all its complex solutions are positive solutions. A support W having n+ 2 elements is called a circuit. We previously showed that the number of non-degenerate positive solutions of a system supported on a circuitW ⊂ Z is at most m(W) + 1, where m(W) ≤ n is the degeneracy index of W . We prove that if a circuit W ⊂ Z sup...
متن کاملThe Theory of Maximally Flat Loudspeaker Systems
A convenient mathematical formulation is given for the absolute lowfrequency response of an electrodynamic direct radiator loudspeaker mounted in a vented or unvented enclosure. The combined effects of speaker Q (ratio of reactance to resistance), enclosure size, and enclosure tuning are shown to control the convergence of the response curve towards ts asymptotic value. Mathematical criteria ar...
متن کاملComputing Invariance Kernels of Polygonal Hybrid Systems
Polygonal hybrid systems are a subclass of planar hybrid automata which can be represented by piecewise constant differential inclusions. One way of analysing such systems (and hybrid systems in general) is through the study of their phase portrait, which characterise the systems’ qualitative behaviour. In this paper we identify and compute an important object of polygonal hybrid systems’ phase...
متن کاملCategory of asynchronous systems and polygonal morphisms
A weak asynchronous system is a trace monoid with a partial action on a set. A polygonal morphism between weak asynchronous systems commutes with the actions and preserves the independence of events. We prove that the category of weak asynchronous systems and polygonal mor-phisms has all limits and colimits.
