Hi..
Can metastability be avoided using fuzzy logic???
Can we afford transmission time delay of few microseconds to process the signal using fuzzy logic???

 

Metastability is a function of the logic circuit and not the type of logic so I don't see that fuzzy logic would be of any help. Fuzzy logic relates to how data is processed, not how individual logic circuit functions are performed.

Perhaps you are thinking of majority logic which is a different thing.

Whether you can afford a few microseconds to process the signal depends upon you application. We have no way of knowing that.
