The classical zero-shifting technique is generalized to cover extraction of complex transmission zeros (TZs) in the form of fourth-order LC sections whereby the jomega- and alpha-axis TZs appear as special cases. Using this approach, bandpass filters can be synthesized in direct coupled resonator forms by pole placement instead of designing them through low-pass prototypes. By using circuit transformations, the resulting direct coupled resonator filter circuits can then be transformed into a variety of cross-coupled forms like a fully cross-coupled form or cascaded N-tuplet form. It is shown that one or more finite jomega-axis, alpha-axis, or complex TZs can be extracted as direct coupled resonator circuit blocks, which can be converted into cross-coupled triplets, quadruplets, or other N-tuplets of resonators. In particular, it is shown that a cascaded quadruplet section can be used to realize a complex TZ quadruplet s(i) = +/-sigma(i) +/- jomega(i), as well as two pairs of jomega-axis TZs, s(i) = jomega(i), and s(k) = jomega(k).

A new representation for the properties of anisotropic elastic fiber reinforced composite materials
Gaith, MS; Akgoz, CY (2005-09-01)
A new procedure based on constructing orthonormal tensor basis using the form-invariant expressions which can easily be extended to any tensor of rank n. A new decomposition, which is not in literature, of the stress tensor is presented. An innovational general form and more explicit physical property of the symmetric fourth rank elastic tensors is presented. A new method to measure the stiffness and piezoelectricity in the elastic fiber reinforced composite and piezoelectric ceramics materials using the no...
Design of Microstrip Quadruplet Filters on Filpro
Oruc, Sacid; Yıldırım, Nevzat (2018-11-02)
In this paper, a simple dimensional design procedure is developed for microstrip/stripline quadruplet filters by starting with direct BP synthesis of a lumped quadruplet with inverter couplings, K14, K12, K23 and K34. K14 is the cross-coupling inverter which creates a symmetric pair of finite transmission zeros (FTZ's) if the sign of K14 is opposite of the other inverters while a complex TZ is created if K14 has the same sign as the other inverters leading to linear phase (flat delay) responses. The LC reso...
A novel two-step pseudo-response based adaptive harmonic balance method for dynamic analysis of nonlinear structures
Sert, Onur; Ciğeroğlu, Ender (Elsevier BV, 2019-09-01)
Harmonic balance method (HBM) is one of the most popular and powerful methods, which is used to obtain response of nonlinear vibratory systems in frequency domain. The main idea of the method is to express the response of the system in Fourier series and converting the nonlinear differential equations of motion into a set of nonlinear algebraic equations. System response can be obtained by solving this nonlinear equation set in terms of the unknown Fourier coefficients. The accuracy of the solution is great...
A new real-time suboptimum filtering and prediction scheme for general nonlinear discrete dynamic systems with Gaussian or non-Gaussian noise
Demirbaş, Kerim (Informa UK Limited, 2011-01-01)
A new suboptimum state filtering and prediction scheme is proposed for nonlinear discrete dynamic systems with Gaussian or non-Gaussian disturbance and observation noises. This scheme is an online estimation scheme for real-time applications. Furthermore, this scheme is very suitable for state estimation under either constraints imposed on estimates or missing observations. State and observation models can be any nonlinear functions of the states, disturbance and observation noises as long as noise samples ...
Recent results on Bayesian Cramér-Rao bounds for jump Markov systems
Fritsche, Carsten; Orguner, Umut; Svensson, Lennart; Gustafsson, Fredrik (2016-07-08)
In this paper, recent results on the evaluation of the Bayesian Cramer-Rao bound for jump Markov systems are presented. In particular, previous work is extended to jump Markov systems where the discrete mode variable enters into both the process and measurement equation, as well as where it enters exclusively into the measurement equation. Recursive approximations are derived with finite memory requirements as well as algorithms for checking the validity of these approximations are established. The tightnes...
