However, close to f0, this fall off may be much steeper, depending on the value of Q, a measure of the filter's resistive losses: Q = 2±f0× L/R. The smaller the value of R is, the larger Q becomes and the steeper the |H(f)| curve becomes, around f0. Sign in to ...
A Finite Impulse Response (FIR) filter is a type of digital filter with a limited number of coefficients that are nonzero, resulting in a response to an impulse that is limited in duration. The impulse response of an FIR filter is identical to its set of coefficients. ...
It is therefore important to filter out the problematic factors from the model. For selecting the set of useful risk factors, our toolkit implements the iterative factor screening procedure of [@gospodinov2014misspecification], the one-step Oracle selection procedure of [@quaini2023tradable], and ...

using the optimum selected wavelet parameters (three-level decomposition, level-1 zeroed out, subband-dependent threshold, a soft-thresholding and spline-based discrete dyadic wavelet transform (DDWT)), which we call a modified wavelet shrinkage filter; this filter is suitable for noisy cryo-ET ...
To filter out genes associated with complex diseases or non-disease phenotypes, we performed the following filter steps. 1) We required that the genes be classified as type 3 (the molecular basis of the disorder is known). 2) We required that the gene have at least one associated phenotype...
and the accuracy of obstacle avoidance is poor. An algorithm that six degree of freedom manipulator moves with end trajectory based on particle swarm optimization was proposed. By analyzing the positive solution of kinematics and inverse solution of kinematics of manipulator, the expected pose of mani...
In this study, both the Kalman filtering algorithm and new type filtering algorithm based on projection filter are employed as procedures to solve the inverse problem. The dynamic system considered in the inverse problem can be written by discrete time model. State equation: (1)zt+1=Φtzt+Γ...
An example high-pass, all-zeros-at-the-origin ladder filter is shown in Fig. 11. Inverse-Chebyshev and elliptic high-pass functions have transmission zeros located on the jω-axis, as well as at zero. To realize the jω-axis zeros requires shunt elements consisting of the series ...
