The superconducting band-pass filter has small insertion loss and excellent out-of-band rejection properties. It has been put to practical use in a number of applications. However, in order to expand its range of application, a tuning technique that can restore the filter characteristics is needed. We propose an automatic tuning system using a trimming library and checked the feasibility of the...

This paper presents a micromachined bandpass filter with miniature size that has relatively outstanding performance. A silicon-based eight-order microstrip bandpass filter is fabricated and measured. A novel design method of the interdigital filter that can create two transmission zeros is described. The location of the transmission zeros can be shifted arbitrarily in the stopband. By adjusting...

The performance of ballistic target interception is critically dependent on the performance of the target state estimation. The estimation performance then strongly depends on the accuracy of the measurement model. The Gaussian uncertainty distribution has commonly been used for representing the statistical properties of sensor noise, due to its mathematical simplicity and effectiveness. Howeve...

In this paper, a simple and efficient design of prototype filters for cosine-modulated filterbanks is proposed. Variable combinational window function with high side-lobe-fall-off-rate (SLFOR) has been used to design the prototype filter for cosine-modulated filterbanks. Cutoff frequency of the filter is optimized to minimize the reconstruction error, which is also selected as an objective func...

Correlation filtering based tracking model has received lots of attention and achieved great success in real-time tracking, however, the lost function in current correlation filtering paradigm could not reliably response to the appearance changes caused by occlusion and illumination variations. This study intends to promote the robustness of the correlation filter learning. By exploiting the an...

We propose a low loss and high selectivity bandpass filter with defected structure on GaN-on-Silicon. GaN-on-Si exhibits insertion due to the presence of parasitic channels at AlN/Si interface. It is necessary strengthen coupling between resonators achieve loss. However, this results in weaker suppression adjacent lower frequencies. The designed consists square spiral defect step impedance reso...

In this paper, a compact ultra-wideband bandpass filter using a back to back Coplanar Waveguide (CPW)-to-microstrip transition structure is proposed. Compared with traditional ultrawideband bandpass filters using hybrid structures, the proposed filter has a sharper selectivity because of two transmission zeros located at the lower and upper edges of the passband, respectively, generated by a mo...
