I want to build a simple computer based function generator and only spend about 10 dollars.
Is it possiable, if so please lt me know about it.

Just download some of this freeware or shareware and you're all set.  Some of it works pretty good up to a certain freq. And some of it is pretty bad.

A lot depends on your computer and sound card.

Good luck.

Yep, use your sound card.
