I want to make a classroom demonstration showing a flipflop in a meta-
stable state. You know, power supply, perfboard, oscilloscope. I'd
like to construct a circuit using a small number of chips, that uses
feedback control to _guarantee_ that the flipflop is operated in a
meta-stable state. My only idea so far is to build a delay locked
loop that schmoo's the relative position of clock and data edges, such
that the long term average output (after RC filter) is 50% of supply.
But this requires a voltage controlled delay line, which isn't really
a catalog part. Does anyone have a better idea of how to demonstrate
meta-stability on a breadboard?
Thanks,
