For receiving broadband satellite signal in airplanes, phased array antenna systems can be used instead of conventional satellite dishes, with advantages such as small weight and better aerodynamic performance. The corresponding beam forming and beam steering system can be implemented in the optical domain. The goal of this master assignment is to analyze and verify the functionality of an opti...

When tracking a large number of targets, it is often computationally expensive to represent the full joint distribution over target states. In cases where the targets move independently, each target can instead be tracked with a separate filter. However, this leads to a model-data association problem. Another approach to solve the problem with computational complexity is to track only the first...

This paper presents an electronically tunable current/trans-impedance-mode biquad universal filter employing only single multi-output current controlled current conveyor trans-conductance amplifier (MO-CCCCTA) and two grounded capacitors. The proposed filter realizes all the standard filter functions i.e. low pass (LP), band pass (BP) and high pass (HP), notch and all pass (AP) filters in the c...

in this article, the effect of cells' radius on the behavior of wavelength switching optical filter andthe effect of the radius of the optical filters' key characteristics such as wavelength resonance onan optical filter based on photonic crystals, have been investigated. currently, the most commonapplied mechanism for designing optical filter based on photonic crystals is using twome...

The trans-admittance-mode (TAM) might act as a transforming bridge for voltage-mode to current-mode conversion. In this study a new low voltage operated electronically tunable TAM biquad filter structure realizing all the seven standard filtering functions namely; low-pass (LP), band-pass (BP), high-pass (HP), regular-notch (RN), low-pass-notch (LPN), high-pass-notch (HPN) and all-pass (AP) fro...

This paper presents a novel third-order cross-coupled rectangular cavity filter by using standard low-temperature cofired ceramic (LTCC) technology, in which the multilayer substrate integrated waveguide (SIW) is implemented. Particularly, the desired filter has a single finite frequency attenuation pole at j4.0 with asymmetrical frequency selectivity. An experimental band pass filter (BPF) has...

-----------------------------------------------------------------ABSTRACT---------------------------------------------------------------Here a modified decision based unsymmetrical trimmed median filter algorithm for the restoration of gray scale, and colour images that are highly corrupted by salt and pepper noise is proposed. This algorithm replaces the noisy pixel by trimmed median value whe...

This paper presents a method for the estimation of Evoked Potentials (EP) using an aposreriori time varying filter based on Discrete Wavelet Transform (DWT). The proposed filter uses Alternate Subensemble Averaging (ASA) to arrive at the signal and noise scalogram estimates. This filter, when applied on the Ensemble Average @A), leads to an improvement in the S m When applied on the individual ...

This paper presents a coaxial combline filter for a class-S power amplifier for an operating frequency of 450 MHz. According to the measurement results, the filter provides a bandwidth of 26 MHz, an insertion loss of 0.55 dB, and a second pass-band only at 2.8 GHz. As the filter dimensions are crucial for the envisaged application, different ways to miniaturise the filter are proposed and their...
