Hi all,

Have a few problems with my assignment.

Circuit is as follows:


Ive derived a truth table and come up with this :


Can someone verify if the above is correct?

Ive then got these 2 logic expressions :

Y = A'D' + C'D' + B'D'
Z = D+ B

What I want to know is (if the above is correct) Is it possible to implement the above circuit using fewer logic gates?

If the complemented inputs are available, how many gates does your solution use? How many gates were used in the original circuit?

The circuit provided uses 3 logic gates as shown above.

I think I need a minimum 3 gates so therefore it would not be possible to implement the circuit with a few number of gates
