Fairly Low Frequency Random Voltage Generator

[Tim Ressel]

My turn. Why not use the recirculating shift register technique? Clock it at a
slow rate and use a handmade R2R ladder. Yields predictable amplitude and
spectrum. Don't forget to use a large shift register, or else you may hear the
repeating pattern.
