Waveguide filters with ridged and unequal width resonators
Yıldırım, Nevzat; Hizal, A (2005-06-17)
Analytical expressions are developed for characterization of ridged / finned waveguides for use in the design of direct coupled waveguide filters with ridged and / or unequal width resonators. The analytical expressions are used to control the harmonic passbands and higher order modes. A survey is made for comparison of responses of waveguide filters using unequal width resonators and unequal ridge resonators. it is found that ridged resonators are more effective in suppressing the spurious passbands in the...
On Miniaturization and Performance Improvement of Planar Wideband Bandpass Filters Without Coupled Lines
Alicioglu, Bulent; Yıldırım, Nevzat (2009-10-01)
Two classical approaches are compared in various respects for the design of wideband planar BPF's without parallel coupled lines, namely, BPF's designed by pole placement with contributing Unit Elements (UE) and inverter coupled resonator filters designed from LP prototypes. It is shown that the circuit obtained by direct BP synthesis is a special case of inverter coupled filter with inverters converted into single Unit Elements. It is also shown that if the inverters are converted into odd number of UE's t...
Non-linear filtering based on observations from Gaussian processes
Gustafsson, Fredrik; Saha, Saikat; Orguner, Umut (2011-03-12)
We consider a class of non-linear filtering problems, where the observation model is given by a Gaussian process rather than the common non-linear function of the state and measurement noise. The new observation model can be considered as a generalization of the standard one with correlated measurement noise in both time and space. We propose a particle filter based approach with a measurement update step that requires a memory of past observations which can be truncated using a moving window to obtain a fi...
