B and D determining the type of the achieved 4th order acoustical overall highpass, using the 2nd order highpass filter to run the driver and using the following equations for adjustment: I) V= VVII) C = C/ fRIII) L= LR/ fIV) V= 1 / (F-1) V) C= Qa/ 2π VI) L= a/ FQ...
sndfilter Algorithms for sound filters, like reverb, dynamic range compression, lowpass, highpass, notch, etc. It's easy to find countless math equations on sound filters, but a bit harder to find simple source code. This library is my attempt at cleaning up and presenting the math-heavy ...
just shifted by 90° and 180° (π/2 and π radians). This is equivalent to a change of the sign of the phase, causing the outputs of the low-pass filter to lag and the high-pass filter to lead.
The edge-detection filter selects a small minority of pixels that are blocky. (InFigures 23-5and23-6, large parts of the images are cropped; on the left and right, not shown, there are large entirely black areas with no edges. But these areas of both figures still contain particle...

To apply the high-boost filter to face normals on a triangle mesh, we re-quire a low-pass filter for smoothing them. We use mean filtering applied to face normals in numerical experiments. The results indicate that the high-boost mesh filtering is a technique effective for 3-D shape ...
first step in writing a filter shader is to understand how to compute the integer sample coordinate corresponding to the current texture coordinate and how to convert sample coordinates back into conventional texture coordinates. The following equations comply with Direct3D's texture-mappin...
Where A(x, y) denotes \(R(x,y){R}^{\text{'}}(x,y){b}^{2}\) to simplify the equations. The last terms in Eqs (10 and 11) are exactly the cosine and sine of the phase only caused by the object. They can be easily extracted by a low-pass filter, which are defined as ...
In such cases, the remaining derivatives on u are computed in Fourier space utilizing both a Tukey-like windowing function and a low-pass filter. Furthermore, the weight functions should be chosen such that the integrals involving the latent fields disappear. To remove the dependence on the ...
The UWB antenna itself can be used to shape the pulse [TAM 12] or the antenna in combination with a band pass filter [MEN 05]. Typically, a monocycle pulse, which is the result of a first derivation of a Gaussian pulse, is used at the transmitting port of commercial radars, such as...
