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.

Grass 5.00 start for idiot, one of the best documentation for Grass beginner users. And this is the Chinese edition, for the ones prefer mother language. From the beginning for Linux participation to the BIOS update, and finally the details setup for GRASS Linux users. Moreover, with my suggestion is that Ubuntu 8.10 is the best package for GRASS 5.00, but it is totally up to you how to choose a platform for this talent open source application.
