Hello all
I'm having the following question:
Design a digital circuit and implement it using 1 half adder and 2 full adders ONLY.
The circuit has 3 bits as input (X) and 3 bits as output (Y).
Y=X+1 (if x<=3)
Y=X-1 (if x>3)
I already designed a truth table and got the simplified functions of Y1,Y2,Y3
where
Y1= X1X2 + X1X3 + X2X3 = XY + Z(X xor Y)
Y2= X xor Y xor Z
Y3= X3'
I spent hours trying to come up with a design that only has 1 half adder and 2 full adders and failed..
Any idea how i can do this?
Thank you.
