可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效,请关闭广告屏蔽插件后再试): 由 翻译 强力驱动 问题: I have an application that captures analog measurements several times a second - to give you an idea how it looks like - here is a sample frame (obviously the curve changes as the measurements chage): alt text http://img829.imageshack.us/img829/3692/curve.png I need this application to record these frames into an AVI or any other video file that would be playable on windows without a custom codec. I've thought of just creating a huge animated GIF file but rewind/pause capability is a must. FLV also will not do. Is there any codec

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效,请关闭广告屏蔽插件后再试): 由 翻译 强力驱动 问题: Is there something that can render Lilypond content to an image, such as mathjax? Also, in my mind it would be nice to open a Stack Exchange forum about music. Such a thing would bring nice functionality to it, like LaTeX in http://math.stackexchange.com and so on. 回答1: Why Lilypond and what else is there? Musically educated people hate ABC notation , but apparently it is ideal for forums just as TeX for math fomulas (e.g. via MathJax). Lilypond is very advanced in its integration (TeX, HTML) and platform support (Windows, Linux,

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效,请关闭广告屏蔽插件后再试): 问题: Under POSIX OS there is signal API that allows to send a signal to process to shut it down with kill and you can catch it with sigaction and do what you need; However, Win32 is not POSIX system, so: How can I handle shutdown events that may come, for example from "End Process" in "Task manager"? What is the standard API for sending shutdown signal to Win32 application? I'm not talking about GUI, I'm talking about TCP/IP server that should be nicely shutdown. that does not run like windows service. 回答1: You get a WM_QUIT message on your first

Binary Search Tree analog

Description Binary Search Tree, abbreviated as BST, is a kind of binary tree maintains the following property: each node has a Key value, which can be used to compare with each other. For every node in the tree, every Key value in its left subtree is smaller than its own Key value. For every node in the tree, every Key value in its right subtree is equal to or larger than its own Key value. Now we need to analog a BST, we only require one kind of operation: inserting. First, we have an empty BST. Input is a sequence of numbers. We need to insert them one by one flowing the rules below: If the

文章目录 1.放大电路的组成原则 2.像电子工程师一样思考――对不同放大电路的改进 3. 设置静态工作点的意义何在 在本文开始之前,先解释一下什么是共射: 即输入输出回路共同经过了发射区,这样的电路就叫做共射电路 1.放大电路的组成原则 静态工作点合适:合适的直流电源,合适的电路参数 动态信号能够作用与晶体管的输入回路 对实用放大电路的要求:共地,直流电源的种类尽可能少,负载上无直流分量 下面,我们会通过电路图一一对这些原则进行剖析 2.像电子工程师一样思考――对不同放大电路的改进 我们先看第一个电路:直接耦合放大电路 看起来和我们上一篇博文中的第一个电路差不多,但是,它有什么问题吗?? 直流电源有点多了,这里有两个,在实际运用中,直流电源能用一个的时候就不会用两个,这无形中会造成成本上的增加 直流电源和交流电源不共地,也就是它们接地端不是同一处。 R b R_{b} R b 会消耗本来就微弱的交流信号,一般我们输入的交流信号都是由传感器获取的外界微弱的信号,如果再经过 R b R_{b} R b 这么一折腾,那传入晶体管的交流信号就微乎其微了 我们来改进一下: 我们现在只是用了一个直流电源 V C C V_{CC} V C C ,至于交流信号所需要叠加的直流信号由 R b 2 R_{b2} R b 2 转化,那么这样我们就可以把交流信号源和直流电压源共地

写在前面:本博文主要是《模拟电子技术》第四章的开篇部分,主要介绍了两种模型:高通电路和低通电路,并且分别对他们的幅频特性和相频特性进行了详细的分析,最后归纳了信号作用在不同频段下的一些应用细节 文章目录 1.高通电路 2.低通电路 在本章里面,我们将要研究的,是频率f对电路放大倍数的影响 我们看f = 1 T = ω 2 Π \frac{1}{T} = \frac{ω}{2Π} T 1 ​ = 2 Π ω ​ , f越大,ω越大,C的容抗 1 j ω C \frac{1}{jωC} j ω C 1 ​ 就越大,进而影响电路的放大倍数 1.高通电路 所谓高通电路,就是输入信号的频率越高(C的容抗大,R的分压多),输出电压越接近输入电压 我们先来看看高通电路的模型: 电容C的容抗为: 1 j ω C \frac{1}{jωC} j ω C 1 ​ ,那么该电路的放大倍数 A u A_u A u ​ 可以表述成: A u = u 0 u i = R R + 1 j ω C = 1 1 + 1 j ω C R A_u = \frac{u_0}{u_i} = \frac{R}{R + \frac{1}{jωC}} = \frac{1}{1 + \frac{1}{jωCR}} A u ​ = u i ​ u 0 ​ ​ = R + j ω C 1 ​ R ​ = 1 + j ω C R 1 ​
