Problem..
simplify b ⊕ c'

What was the symbol between b and c'? Kind of hard to help if we don't know what the problem is.

It looks like an exclusive OR to me, as in 'one or the other but not both':

A B X
0 0 0
0 1 1
1 0 1
1 1 0

So A XOR B = A'B + AB'

So what does that tell you about B XOR C'?

 

[Mark44]

Zryn,
How do you get XOR out of ⊕?

 

[Zryn]

That was the symbol I was introduced to, and used, throughout my University life, essentially a + inside a circle.

Doing a Google search for "XOR Symbol" confirmed this.

If we assume that the symbol is part of a Rorschach test, I'm going with 'XOR Symbol', but what do you see =P?

 

[Mark44]

Maybe it's my browser - I don't see anything but an empty box.

 

[Zryn]

It's a pretty shabby XOR symbol, as far as XOR symbol's go really, but it does the job.

 

[Mark44]

Yeah, all I see is an empty box.

thank u for the such an idea..
so..
when A XOR B' = AB + A'B'

correct?

 

[Zryn]

Yes, you can algebraically replace each B with B', so A'B + AB' becomes A'B' + A(B')' = A'B' + AB.

Proof below just for completeness:

A B (B') X
0 0 (1) 1
0 1 (0) 0
1 0 (1) 0
1 1 (0) 1

So A XOR B' = A'B' + AB.

All good!
