Adjustable noise

[Mitchell Hudson]

    I want to make a noise source with some adjustability. I have made a
schematic which mostly plagerized from EFM and forest Mims. The idea is
to make a noise source for a sample and hold with ability to scale and
offset the noise. I have put a schematic on my web site.

    Of course it must be pointed out that I really have no idea what I
doing. so any suggestions would be greatly appreciated.

Thanks
