Position theĬursor over the correct vertical wire.

You will be dragging a wire from the AND gate. Positioned correctly, the word 'Wire' will appear within theĬursor. Select the pencil tool and place the cursor on The ones we drew in class you will wire the AND gates to You will see that is is a sum-of-products circuitĭesign, but the AND gates aren't wired. Now you are ready to try a circuit of your own.īy left-clicking the link. (It does, so this circuit computes the Boolean function specified

The output, F, reflects the value specified in the truth table. Handout to see which variables change at each step.) Check that Now run through all eight possible combinations ofĪ, B, and C in binary number order. Observe whether the output, F,Ĭhanges state. State of the variable and its complement change as shown by the The circuit and change its state by left-clicking.
