-Based on feedback control of the system of thought, from AC-DC converter circuit, DC-DC converters, stepper circuit module and display module 4 module circuit switching power supply. AC-DC converter circuit using full-wave rectifier part of the circuit form of bridge rectifier, DC-DC converter to TL494 have the main core of the design and add a simple RC filter circuit and discharge circuit posed by the loop controller. It can change the pulse width signals into changes with the pulse width is proportional to the DC signal, and thus realize the closed-loop single-loop control. By the single-chip microcomputer to control the number of locator X9241 resistance, thereby control the output voltage. LCD1602 constituted by the display module. Platform: |

Description: Uniform random number generators
by Agner Fog, 2001 - 2007
randomc.zip contains a C++ class library of uniform random number generators of good quality.
The random number generators found in standard libraries are often of a poor quality, insufficient for large Monte Carlo calculations. This C++ implementation provides random number generators of a much better quality: Better randomness, higher resolution, and longer cycle lengths.
The same random number generators are available as libraries coded in assembly language for higher speed. These libraries can be linked into projects coded in other programming languages under Windows, Linux, BSD, etc. The library files are available in the archive asmlib.zip.

Description: 均匀分布伪随机数发生器
伪随机数在计算机软件设计中有很广泛的用途。本文介绍了基于数学方法的利用计算机产生伪随机数的一种方法，即线性同余法，任何伪随机数的产生都是运用递推的原理来生成的。以及在Visual C++环境中产生伪随机数的两个重要函数，rand和srand函数，正确地使用这两个函数是产生性能良好的伪随机数的关键
-Uniformly distributed pseudo-random number generator, pseudo-random number in the computer software design in a very wide range of functions. This paper introduces the mathematical methods based on the use of computer generated pseudo-random number in a way that the linear congruence method, any pseudo-random number generated is to use the principle of recursive generated. As well as in Visual C++ Environment pseudo-random number generated two important functions, rand and srand functions, proper use of these two functions is the good performance of the pseudo-random number key Platform: |
