[sdiy] multiplier questions/experiments AD633

[dan snazelle]

its interesting, these circuits are coming out FUZZED.


I will try some control voltages and see if they work better than AUDIO.


of course I want to see what else is possible with multipliers....going through the non-linear handbook looking for stuff...any ideas?



thanks
