At 14:30 I will give a short introduction to my thesis You are most welcome to attend the introduction, the defense and the reception afterwards. Abstract Tunable on-chip Radio Frequency (RF) filtering is highly desirable for cost effective wireless communication devices. As mobile wireless devices increasingly support multiple RF-bands, tunable RF filtering is wanted. The tremendous growth of ...

This paper describes a combination of a Weaver mixer and an N-path filter for a superheterodyne receiver with a reconfigurable frequency plan. It uses an N-path topology driven with two different frequencies, effectively realizing a frequency shift together with band-pass filtering. To reduce transfers via harmonics other than the fundamental, a harmonic rejection scheme is used. A 28 nm FDSOI ...

We demonstrate a Fock-state filter which is capable of preferentially blocking single photons over photon pairs. The large conditional nonlinearities are based on higher-order quantum interference, using linear optics, an ancilla photon, and measurement. We demonstrate that the filter acts coherently by using it to convert unentangled photon pairs to a path-entangled state. We quantify the degr...

A new frequency domain ANC algorithm based on the Kalman filter is presented. This algorithm has on-line secondary path modeling and is designed to minimize the effects of large secondary path changes on the acoustic noise level. It is based on the Overall Modeling Algorithm with a careful controller and estimation of the secondary path changes. Due to its frequency domain implementation the sy...

A phenomenological model was developed to describe responses of high-spontaneous-rate auditory-nerve (AN) fibers, including several nonlinear response properties. Level-dependent gain (compression), bandwidth, and phase properties were implemented with a control path that varied the gain and bandwidth of tuning in the signal-path filter. By making the bandwidth of the control path broad with re...

In this paper, an active control structure used piezoelectric stack actuator is built to suppress vibration due to internal incentive in gear transmission. Because the gear system is timevariant and unknown, an offline modeling technique is unable to tracking the changes in the secondary path, an adaptive filter algorithm used online secondary path modeling method is proposed to the active vibr...

XML path queries form the basis of complex filtering of XML data. Most current XML path query processing techniques can be divided in two groups. Navigation-based algorithms compute results by analyzing an input document one tag at a time. In contrast, index-based algorithms take advantage of precomputed numbering schemes over the input XML document. In this paper we introduce a new indexbased ...

The presence of near-end interferences and echo path changes make it essential for an adaptive filter to vary its learning rate according to corresponding conditions. In this paper, a robust step-size control algorithm which is based on the optimization of the square of the bin-wise a posteriori error is proposed. To prevent the adaptive filter from diverging in the presence of interferences, c...

In the FIR filter design the MCM block optimization plays a vital role to reduce the critical path which is due to the product accumulation section. The critical path delay is reduced by using the Transposed direct form (TDF) FIR filter is proposed. The filters which have large number of multipliers. The partial products by using OTFC-LRRS multiplier is implemented in the FIR filter. The array ...
