Dual-mode ring resonator filters are implemented with asymmetric inductive perturbation for creating transmission zeros on both sides of the passband. In analysis, dependence of the resonance modes and the zeros on positions and sizes of both the inductive and capacitive perturbations is investigated. Under certain conditions, the even- and odd-mode(More)
Source-load coupling is inserted to a compact filtering branch-line coupler for generating transmission zeros. Quarter-wavelength stepped-impedance resonators are employed as the resonating elements for circuit miniaturization. All inter-resonator couplings are of inductive type, and the source-load coupling between adjacent feeds is of capacitive type.(More)
Abstract When influence coefficient (IC) method is used in rotor balancing, it is possible that serious errors could be resulted in unbalance determinations due to the contamination of measurements and IC matrix being ill-posed. In this study, the availability of least squares algorithm (LSA) and Tikhonov regularization (TR) is studied by error estimations(More)
