说明:  摘要:介绍一种基于8051F单片机的数字音频信号源,利用单片机用DDS算法产生音频信号,通过数字电阻衰减器控制音频信号幅度,在0~100dB的幅度范围内实现1dB的步进值,系统计算机接口实现了集中多路衰减量的控制。 关键词:音频;单片机;控制;数字/数字音频信号源;电阻衰减器;C8051F330;CD4053(Abstract: A microcomputer-based 8051F digital audio signal source using DDS algorithm for single-chip computer generated audio signals, digital resistor attenuator control of the audio signal amplitude, in the range of 0 ~ 100dB achieved within 1dB of step value, the system computer interface of the centralized multi-channel attenuation control. Keywords: audio microcomputer control digital/digital audio signal source resistor attenuator C8051F330 CD4053)

    总个数确定后,每张盘curDisk的移动方向maybe_To是确定的且唯一的:如共有三个盘时,盘1始终向左移动。 这里,将柱子由左向右看成A(源柱子Source),B(借助的柱子Borrow),C(目标柱子Target). A的左看成C,B的左看成A,C的左看成B; A的有看成B,B的右看成C,C的右看成A; 每张盘的移动方法(因为不可能连续两次移动相同的盘!): 一个盘curDisk现在在 柱子curStick上,那么curDisk另一个柱子(3个中除了2个的另1个) 只要有选择的选择一个柱子curStick,分析、判断其最上面的盘curDisk的能否向curDisk确定的唯一的方向移动;移动 完后 再 选择 另一个 柱子 分析 判断 就可以完成了 (这个算法特别适合于人玩这个“弱智”(我有同学这么说)游戏,我玩我的文曲星pc1000a上的Hanoi 9层游戏,需要5分钟就可以移动完毕)-total number identified, each set curDisk maybe_To direction of the movement of which is determined only : If there are three disk, was always left a mobile. Here, the columns from left to right as A (source pole Source), B (using the pole Borrow), C (target pole Target). A left as C, B to the left as A, C on the left as B; A as the B, B on the right side as C, the right as A; each set of mobile methods (as it is impossible for the same two mobile disk!) : a set curDisk curStick now on the pole, then curDisk another pole (three in addition to two other one), when given a choice, choose a pole

  • VLMpc
    Vortex lattice analysis and design: VLMpc(John Lamar s two surface vortex lattice program, developed at NASA Langley. The program treats two lifting surfaces using up to 200 panels. Vortex flows are estimated using the leading edge suction analogy. This program was typed in the NASA TN D, which contained the listing, by students in Applied Computational Aerodynamics nearly 10 years ago. John Lamar didn t have a copy of the code anymore. It has been modified to run in WATFOR, and to produce 80 column output. Now it runs in Compaq Visual Fortran. In November 2002 an executable has been added. The source now includes PC directory code specific to PCs. )
