Match function generator output phase to line phase

I'd avoid using a 741 unless you already have them, not anything else, and are tight with money. Otherwise for Schmidt triggers, if I don't toss one together with discrete transistors, I'll grab a ...

A Schmitt trigger also is a comparator. The reference input is internal, but not in the same way as an comparator. The rise and fall times are determined by the speed of the internal transistors in ...
