Davy said:Hi all,

How to Build a XOR with a MUX(2 to 1) and a invertor?

Any suggestions will be appreciated!

Best regards,

Davy

Input A of MUX = S1

Input B of MUX = NOT S1

Input S of MUX = S2

Working out the Truth Table....

If S1 and S2 are 0, the MUX output is S1, which is 0

If S1 and S2 are 1, the MUX output is NOT S1, which is 0

If S1 is 1 and S2 is 0, the MUX output is S1, which is 1

If S1 is 0 and S2 is 1, the MUX output is NOT S1, which is 1

Do I get the job?
