Thedefinition of low pass filteror LPF is one kind of filter used to pass signals with low frequency as well as attenuate with high frequency than a preferred cut-off frequency. Thelow pass filter frequency responsemainly depends on theLow passfilter design. These filters exist in several forms...

In this paper, the formulas for the electric response of a low-frequency RC filter with liquid crystal characterized by complex electric permittivity are derived. One Debye-type relaxation is assumed in the calculations. The influence of strengths and relaxation time (fr...

A method based on low-pass signal filtering and empirical mode decomposition was applied to eliminate high-frequency noises and low-frequency trends included in signals measured in seakeeping test.A signal is deposed by low-pass filtering before empirical mode decomposition,which can make the signal'...
Pole-zero distribution for Ha(s)Ha(-s) for an elliptic lowpass filter with n = 6. The series in Eqs. (4.120) and (4.122) are fast converging. In many filter design calculations, up to four or five terms in the series will provide sufficient accuracy. In Example 4.4 the computation ...
a surrogate neural network model was used to design a microstrip power divider and a low-pass filter (LPF). The suggested technique improves the performance and frequency response of a wide range of microwave devices. Their efficient design is a result of using the surrogate model of the propos...

Introduction The article proposes a low-pass filtering method for Poisson-distributed data time series, based on a specially developed digital low-pass filter with ...
The experimental results differ slightly from the theoretical and a minor time delay is observed in the response due to the low-pass filter used to eliminate the sensor noise. However, the system is capable of completing the commanded maneuver with an accuracy of 1.5 deg tightly following the ...
