tangent ripple

Equivalent series resistance ESR of capacitance The prevailing view is that an external capacitance of relatively large capacity with a small equivalent series resistance (ESR) can well absorb the peak (ripple) current at fast conversion. However, sometimes such a choice can cause the voltage regulator (especially the linear regulator ldo) instability, so it is necessary to choose a reasonable capacitance of small capacity and large capacity. Always r

In PS can also make animation, do you know? Making animation in PS is simpler and the effect is realistic. So how to implement animation in PS? Now demonstrates a flow of water animation production process for everyone to refer to. 　　Steps/methods: 1. Execute "FILE--Open" command 2, in the "Open" dialog box to select the flow of water to create a static picture, click the "Open" button to open the picture 3. Select the water section with the "Quick selecti

　　Distort (distort) filters achieve a variety of effects by applying distorted distortion to an image. 　　1, Wave ( wave filter ) 　　function: make the image ripple effect. 　　Adjust parameters: 　　Number of generators: control the number of generated waves, ranging from 1 to 999, 　　Wavelength: Its maximum and minimum determine the distance between adjacent peaks, the two values are mutually restricted, the maximum value must be greater than or equal

And promises to tell you about the important tools in 3D geometry, tangent space, in the background. Today, we are here to tell you about the next part of the work.Tangent SpaceAs we know, in the previous article,

I. Summary Previous ArticleArticleThis article introduces how to design a filter using the fdatool toolbox. For details, see"Filter Design and file generation based on fdatool toolbox in MATLABHere are several examples to illustrate the process of designing an FIR Filter Using Matlab. Ii.

RefersThe ripple is the uneven texture on the front of the finger. Although fingerprint is only a small part of human skin, it contains a lot of information. Fingerprint features can be divided into two types: general features and local features. General FeaturesIt refers to the features that can be directly observed by the human eye, including the basic pattern, pattern area, core point, triangle point, style line and number of lines. The basic patte
