In the logic circuit shown in the figure, input A goes to a NOT gate. The output of the NOT gate and input B go into an AND gate. The output of the AND gate and input A go into an OR gate, whose output is Y. For all inputs, the circuit gives the same output as a single

Fig. 1: Input A goes to a NOT gate. The NOT output and input B go to an AND gate. The AND output and input A go to an OR gate, whose output is Y.
