Ex-OR Gate

Question

if xy = 0 then x xor y is equal to ________

Comments

xy=0 has 3 possibilities:

1) x=0, y=0 then x xor y = 0

2) x=0, y=1 then x xor y = 1

3) x=1, y=0 then x xor y = 1

---

x⊕y = (x⊙y)' = (xy+x'y')'
since xy=0

∴ x⊕y = (x⊙y)' = (xy+x'y')' = (x'y')' = (x+y)

x⊕y = (x+y)
so possible values of x and y are 0 and 1 

x⊕y = 0 or 1

Answer 1

Depends can be 0 or 1

If both are 0 (x and y) then exor will be 0

If either one of them is 1 other is 0 it will be 1
