On the optimum area-balanced filters for nuclear spectroscopy

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1996
Abstract The minimum noise Area-Balanced (A-B) filters for nuclear spectroscopy are disentangled in the sum of two optimized individual filters. The former is the unipolar finite cusp filter, used for pulse amplitude estimation but affected by baseline shift errors, the latter is a specific filter used for baseline estimation.

Balanced-realization based adaptive IIR filtering

1999 IEEE International Conference on Acoustics, Speech, and Signal Processing. Proceedings. ICASSP99 (Cat. No.99CH36258), 1999
Balanced-realizations are attractive for adaptive filtering, due to their minimum parameter sensitivity and due to their usefulness in model-reduction problems. A balanced-realization based adaptive IIR filtering algorithm is presented. The proposed algorithm uses a stochastic-gradient based search technique to minimize the output error.

Balanced and Closed-generated Filters In Frames

Quaestiones Mathematicae, 2003
We introduce the notions of balanced filters and closed-generated filters in frames and use them to give a new characterisation of normality for frames, and hence, due to normality being a conservative property, a new characterisation of normality for topological spaces.

Balanced-to-Balanced Gysel Power Divider With Bandpass Filtering Response

IEEE Transactions on Microwave Theory and Techniques, 2013
In this paper, the balanced-to-balanced Gysel power divider is proposed with bandpass filtering response for the first time. The component is based on a ring structure and designed with an extended coupled-resonator circuit model. The characteristic impedances, electrical lengths, and isolation resistance are calculated analytically by our derived ...

Balanced Filters for an Annular Counter

Advances in X-ray Analysis, 1984
Annular counters are finding increasing application in x-ray diffraction. They are well suited for detection of weak diffracted beams because of their ability to capture an entire Debye ring. This is especially true in the case of microfocus diffractometers, where the Illuminated sample area may be a spot less than 100 microns in diameter ...

A Balanced Filtering Branch-Line Coupler

IEEE Microwave and Wireless Components Letters, 2016
A balanced filtering branch-line coupler is proposed for the first time. The proposed design is realized by coupled microstrip lines and coupled-line-fed coupling structures. Based on this, the proposed design not only exhibits the functions of power dividing and filtering for differential-mode signals, but also can suppress the common-mode noise ...

A Planar Multiband Balanced Bandstop Filter

2018 IEEE MTT-S Latin America Microwave Conference (LAMC 2018), 2018
This paper introduces for the first time, a novel architecture of differential (balanced) bandstop filter (BSF), which can realize an arbitrary number of stopbands with arbitrary order. The design incorporates in-series cascade of K N-band sections in a branch line structure to realize a K-th order N-band balanced BSF transfer function. The common-mode

Single-to-balanced BAW filter combining CRF with lattice filter

IEEE Ultrasonics Symposium, 2005., 2006
Although FBAR filters have successfully penetrated the CDMA duplexer market, they still cannot displace the SAW filters in traditional RF front-end filter applications. Most of present cell phone systems like GSM or WCDMA require the filter device to have both single- to-balanced conversion and impedance transformation functions.

Armlets and balanced multiwavelets: flipping filter construction

IEEE Transactions on Signal Processing, 2005
In the scalar-valued setting, it is well-known that the two-scale sequences {q/sub k/} of Daubechies orthogonal wavelets can be given explicitly by the two-scale sequences {p/sub k/} of their corresponding orthogonal scaling functions, such as q/sub k/=(-1)/sup k/p/sub 1-k/. However, due to the noncommutativity of matrix multiplication, there is little

Balanced log-domain wavelet filters

SPIE Proceedings, 2006
To meet the ultra low-power and low-voltage applications,this paper presents a analog VLSI implementation of DOG wavelet transform using a balanced log-domain integrator with class AB. The circuits of implementing wavelet transform are composed of analog filter ,whose impulse response is the required wavelet . Levenbery-Marquardt nonlinear least square
