Complex Low-Pass Filters
, 2002
"... Quadrature zero-if transceivers suffer from the imbalance of the I and Q paths. By using a complex low-pass filter topology instead of a conventional pair of real low-pass filters, this imperfection can be reduced. Both analytical and numerical analysis show that the proposed technique is significan ..."

THE NOVEL ARC LOW-PASS FILTER
"... In this paper, we propose a new form of the amplitude response for designing low-pass filters, that is defined by a modified arctan-gent function in the frequency domain. This is a parameterized and very smooth function which can be used for any tolerance scheme with given specifications. The filter ..."

Contraction, smoothness, and low-pass filtering
- In ICASSP 2004
"... We introduce a generalized definition for “low-pass ” filters that covers time-varying and nonlinear systems under the same umbrella. We show that the qualitative concept of signal smoothing can be made precise through the concept of contractions in probabilistic metric spaces. For illustration, we ..."

Low-Pass Filtered Volumetric Shadows
"... Fig. 1. Volume renderings of a numerical flow simulation data set. (a) Volumetric ambient occlusion and specular highlights provide only local visual cues for perception of spatial depth. (b) Illumination from three orthodirectional light sources with single scattering provides global visual cues bu ..."

but introduces disturbing patterns and is too dark. The same setup visualized with our novel model using (c) a small and (d) a large volumetric region for low-pass filtering to avoid disturbing high-frequency shadow patterns. Abstract—We present a novel and efficient method to compute volumetric soft shadows
Analysis of simple two-capacitor low-pass filters
- IEEE Trans. Electrom. Compat
, 2003
"... Abstract—The performance of typical low-pass capacitor fil-ters is limited by the mutual inductance between the input and output sides of the filter. This paper describes how two appropri-ately spaced capacitors can be used to construct a low-pass filter with significantly better high-frequency perf ..."

, 2011
"... ABSTRACT This paper considers the problem of construction of low-pass filters on the unit sphere, which has wide ranging applications in the processing of signals on the unit sphere. We propose a design criterion for the construction of strictly bandlimited low-pass filters in the spectral domain w ..."

and Receiver with Multi-Band Low-Pass Filter
"... Abstract—This paper presents a full-CMOS transmitter and receiver for VDSL2 systems. The transmitter part consists of the low-pass filter, programmable gain amplifier (PGA) and 14-bit DAC. The receiver part consists of the low-pass filter, variable gain amplifier (VGA), and 13-bit ADC. The low pass ..."
