XOR Using NAND gates
Hi,
I didn't see a posted solution to this one.... the solution I came up with required 5 NAND gates.
just for clarification:
* = AND, ! = NOT, + = OR, @ = NAND gates
Z = (!x*y) + (x*!y) // XOR gate equation
= ![!(!x*y) * !(x*!y)]
= ![(!x@y) * (x@!y)]
= (!x@y) @ (x@!y)
Where !x = x@x and !y = y@y.
