Consider the digital circuit given below.
Both the NAND gates have finite and unequal propagation delays. The present input conditions are:
A = B = 0
If the input conditions are changed simultaneously to A = B = 1, the possible outputs of X and Y are
1
X = 0, Y = 0
2
X = 0, Y = 1
3
X = 1, Y = 0
4
X = 1, Y = 1
