Since the achievable gain of transistors typically falls off as the frequency increases, an equalization filter with positive gain slope is necessary to compensate for the gain roll-off of broadband amplifiers. This paper proposed an novel equalizer structure and design a equalization filter by applying this novel structure and a modified SIW-PBG (Substrate Intergrated Waveguide-Photon BandGap)...

A point set obtained by laser altimetry represents points from not only the ground surface but also objects found on it. For civil works applications points representing the surface of non-ground objects have to be removed from the point set in a filtering process. This paper describes modifications made to an existing “slope based” filtering algorithm, and presents some results obtained from t...

When plane-wave destruction (PWD) is implemented by implicit finite differences, the local slope is estimated by an iterative algorithm. We propose an analytical estimator of the local slope that is based on convergence analysis of the iterative algorithm. Using the analytical estimator, we design a noniterative method to estimate slopes by a three-point PWD filter. Compared with the iterative ...

The use of Kalman filtering techniques for landslide monitoring has proved effective as a tool estimating and predicting land displacements. Ground-Based Synthetic Aperture Radars (GBSAR) are popular remote sensing instruments able to provide displacement maps the investigated area, with submillimeter precision. These outperform other sensors in several respects, such all-weather all-day monito...

OBJECTIVES Performance of cochlear implant (CI) users on linguistic intonation recognition is poorer than that of normal-hearing listeners, due to the limited spectral detail provided by the implant. A higher spectral resolution is provided by narrow rather than by broad filter slopes. The corresponding effect of the filter slope on the identification of linguistic intonation conveyed by pitch ...

We present a simple design rule for diode-laserpumped quasi-three-level lasers by using the M2 factor. The validity of this model was demonstrated by diode-pumped Yb:YAG laser experiments. The maximum output power of 1.33 W and optical slope efficiency of 63% were obtained in a 400m Yb:YAGchip miniature laser. Using a 200m Yb:YAG chip, a 70% optical slope efficiency was reached. In a coupled-ca...

Analysis and performance evaluation of a macro-bend fiber based interrogation system for a Bragg grating sensor array is presented. Due to the characteristic properties of the macro-bend fiber filter such as polarization and temperature dependence and the total noise associated with the ratiometric system, a best fit ratio slope is required to interrogate multiple FBGs whose peak wavelengths ar...
