Demorgans laws are a way to switch from postive to negative logic or vice versa. Reasons to use Demorgans laws is to reduce the condition set. if(reduce stuff here) Most times you end up using a truth table or better techniques like a kmap for hard problems however some are trivial like the following: Serial line detector: based on the value 0 or 1 and the current state a specific operation needs to happen.
