[sdiy] (oops) EN #76 question

[Russell McClellan]

Bernie Hutchins wrote a rather interesting and involved discussion of
the circuit described in this thread in the latest edition of
electronotes - http://electronotes.netfirms.com/EN212.pdf

In addition to reprinting the circuit in question, he provides some
great observations, including an interpretation of the DACs as FIR
filters on a white noise signal.
