High pass/Low pass 都是频域特性，如果要分析频域特性，那就要把拉氏变换转换成傅里叶变换（如果傅里叶变换存在的话），这个转换简单直接，就是传递函数在s平面的虚轴上的投影（让s=jw）。引用自ADI：The Scientist and Engineer's Guide to Digital Signal Processing The Laplace Transform (analog....
With a 25-sec low-pass filter, the noise level at short periods (less than 1 hour) is low enough to detect events as small as 3 nanoradians. ... DR Sherrod,RM Krug,M Ripepe,... - 《Agu Fall Meeting Abstracts》 被引量: 1发表: 2005年 An exploratory study of knock intensity in ...

The Hermite kernel is constructed by using the discrete singular convolution (DSC) algorithm, which provides a systematic generation of low-pass filter and its conjugate high-pass filters. The high-pass filters are utilized for approximating spatial derivatives in solving flow equations, while the ...
A 3 kHz, 12 dB/octive high-pass filter is used to attenuate RFI primarily from power line harmonics. The signal is fed to a LeCroy WaveJet 354 with a 250 kHz low pass filter and a sampling rate of 250 kS s−1. The magnetic field is measured using a 200 turn, 1.2...
12.0 2.8 Low resolution, max z, 2x2 scale 46 11.7 2.3 Table 23-1 shows the cost for a pixel shader of 73 Shader Model 3.0 instructions. We artificially padded our shaders with an unrolled loop ofmadinstructions to simulate a complex, in-game shader. Table 23-2 shows the result ...
we assume that cosmic rays can either escape as neutrons (which are not magnetically confined) or, directly from the borders of the production region within their interaction length or Larmor radius (whatever is smaller)38, which leads to relatively hard spectra acting as a high-pass filter16....
The essential equations to design different parts are presented. Furthermore, the selection of elements based on the design guidelines and obtained values are described in detail. It should be noted that the proposed converter has a symmetric structure. In this condition, the elements in the ...
Noting that the potential function ϕ(xo) is real, we obtain from equations (12) and (20) (24) where sin χ(u) is called the ‘phase contrast’ transfer function.68–70 This equation indicates that the image intensity I(xi) is greatly affected by defocusing through sin ...
Subsequently, the locations were refined by applying the double-difference method (hypoDD24 code, version 2.1), starting from the hypocentral parameters determined from the absolute locations and solving the double-difference equations in the same 3D P- and S-wave velocity model used for absolute ...
