Also; you means at fullscale input=10V & Output puls scale is 10V/div?
No, sorry I dont no yet, but I think, that for your counter is a changing not relevant. What about min to max. duties pls?
Otherwise the simplest way is to have garanted 50% of duty if you apply a D-FF connected as divide by two circuit!
