One goal of our summer projects is to create programs for generation of test signal data. As a simple example, we can use a Gaussian-distributed random number generator, to which we can add a simple sine-wave (chirp) generator to simulate standard SETI signals. In the C standard library, I don't think there is a Gaussian distributed generator.
In Numerical Recipes, there are Gaussian random number generators. There are open source variants available. Any suggestions on what should be incorporated into our open source projects?
