3.1.5 XOR
In SR line diagram, the two commutator In SR, the symbol of
contacts for XOR are connected in serial XORis shown as follows:
as follows:
I1 I2
When the statuses of all the inputs are not the same, the output status of XOR is 1.
When the statuses of all the inputs are the same, the output status of XOR is 0.
Logic frame of XOR:
I1 I2 Q
0 0 0
0 1 1
1 0 1
1 1 0
