hi there-
i'm learning about electronics and working with an LM319. i'm using a standard window comparator circuit (http://datasheetcafe.databank.netdna-cdn.com/wp-content/uploads/2015/09/LM319-Circuit.gif).
instead of getting V+ when the signal is in range, i'd like to get an "off" signal - and I'd like the V+ while the signal is out of range. simply changing the "pull-up" resistor to a "pull-down" resistor doesn't seem to be the solution.
any suggestions?
