Why K-map has states in sequence of 00,01,11,10 instead of 00,01,10,11?

Question

Why K-map has states in sequence of 00,01,11,10 instead of 00,01,10,11?

Answer 1

It's because in the first sequence, each entry differs in only one bit whereas in the second sequence the transition from 01 to 10 changes two bits which produces a race condition. In asynchronous logic, nothing ever happens at the same time, so 01 to 10 is either 01 00 10 or 01 11 10 and that causes problems.

Answer 2

This is because if we write 00 01 11 10 then in between two there is a difference of two bits and as smparkes told that asynchronous cannot take two values a time so that is the only way left now. As we take gray code in a similar way gray code of 00 is 00, of 01 is 01, of 11 is 10 and of 10 is 11. In this way k map is numbered.

Answer 3

In the process of simplification, when 2 minterms, with one bit differing,r ORed, one variable gets eliminated as 1 + 0 = 1
