In the following combination of logic gates, the outputs (y,z) are respectively.

Step-by-step solution

For Circuit I: The inputs are 1 and 1 . The second input passes through a NOT gate, so it becomes 1 = 0 . These signals ( 1 and 0 ) are fed into a NAND gate. The output Y = 1 0 = 0 = 1 . For Circuit II: The inputs to the OR gate are 0 and 1 . The output of the OR gate is 0 + 1 = 1 . This output ( 1 ) and the third input ( 0 ) are fed into an AND gate. The output Z = 1 0 = 0 . Therefore, the outputs (Y, Z) are (1, 0) . Answer: 1, 0
