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.
