I often need a simple function generator. Just to generate a certain frequency. After all the years I ve worked with electronics, I still haven t got me one. Even though I need it now and then, I just couldn t seem to justify the cost of one. So, standard solution - build one yourself. I designed a simple sinewave generator based on a Analog Devices AD9832 chip. It will generate a sinewave from 0.005 to 12 MHz in 0.005 Hz steps. That s pretty good, and definitely good enough for me ! But while waiting for the AD9832 chip to arrive, I came up with a very simple version of the DDS synth, using just the 2313 and a resistor network.

Good morning, dear teachers. I am very glad to be here for your interview. my name is xx.I am 21 years old. I come from Dafang, a small town of Guizhou province. My undergraduate period will be accomplished in East China Jiaotong University. I major in electrical engineering and automation. I am interesting in computer, especially in program design. I am a hard study student, especially in the things which I interesting in. I am a person with great perseverance. During the days I preparing for the postgraduate examination, I insist on study for more than 10 hours every day. Just owing to this, I could pass the first examination finally. I am also a person with great ambition.

两台处理机A 和B处理n个作业。设第i个作业交给机器 A 处理时需要时间ai，若由机器B 来处理，则需要时间bi。由于各作 业的特点和机器的性能关系，很可能对于某些i，有ai >=bi，而对于 某些j，j!=i，有aj<bj。既不能将一个作业分开由两台机器处理，也没 有一台机器能同时处理2 个作业。设计一个动态规划算法，使得这两 台机器处理完成这n 个作业的时间最短（从任何一台机器开工到最后 一台机器停工的总时间）。研究一个实例：（a1,a2,a3,a4,a5,a6）= （2,5,7,10,5,2）；（b1,b2,b3,b4,b5,b6）=（3,8,4,11,3,4）
