I know somebody makes this, I just don't remember who.
Input 1: A pulse train of frequency 'x', and duty cycle of 'y'
Input 2: A pulse train, also of frequency 'x', but a duty cycle of 'z'.
Output A: ON is when
Input 1 is ON for a long time, or OFF for a long time
-or-
Input 2 is ON for a long time, or OFF for a long time
-or-
One of the inputs changed state twice, while the other input changed state only once (dual Missing Pulse detection).
In the old days, I would have gone to Eagle, Dynapar, Veeder Root, et al.
But, in the new days, I would think this would be a DIN rail mountable thing.
