How to gather low voltage analog signal

[peelingthunder]

My source has a low voltage output. How would I go about gathering the signal, digitize it and get it on a PC? What kind of interface would I need? Complete noob here.
Any help is really appreciated. Thanks!

if you want a ready-made solution you can use data acquisition card and associated software. Matlab also support data acquisition card.

Depending on the signal, you could also capture it directly to the PC via the microphone input and let your sound card digitize it.
