SUPPRESSING_OSCILLATION

Use of positive feedback to pin 5 of comparatorgives sharp and clean output transitions even with slow triangle-wave inputs, with no possibility of comparator bursting into oscillation near crossing point. Input resistors should not be wirewound.Circuit will handle triangle-wave inputs up to several hundred kilohertz.—P.
