We are given question 12, which involves an integrated circuit diagram. We need to determine the correct output at ports 3 and 10, given that inputs 1 and 0 are applied to ports 1, 2 and 8, 9 respectively.

1. Problem Description

We are given question 12, which involves an integrated circuit diagram. We need to determine the correct output at ports 3 and 10, given that inputs 1 and 0 are applied to ports 1, 2 and 8, 9 respectively.

2. Solution Steps

The diagram shows a series of logic gates. Let's analyze the circuit:

The input at port 1 is 1 and the input at port 2 is

0. These go to the first NAND gate. A NAND gate outputs 0 only if both inputs are 1, otherwise it outputs

1. So the output of the first NAND gate is 1 (since the inputs are 1 and 0). This output goes to port

3. The inputs at port 8 is 1 and the input at port 9 is

0. These go to the second NAND gate. Similarly, the output of the second NAND gate is 1 (since the inputs are 1 and 0). This output goes to port

1

0. Therefore, the outputs at ports 3 and 10 are both

1.

3. Final Answer

(4) 1,1
