    Hi Kewl,

    You willl need to do a little bit of homework on this one ;) however, I will give you a clue.

    The first Op-Amp is used to either cut the negative part or to invert it. You will need to figure which one it is since I am not telling you :)!

    The second Op-Amp is used to filter the signal to DC.

    Hope this helps without helping you too mutch. Tell us your progress and/or other questions if needed.

    Simon
