The logical equation for the logic circuit in Figure 3 is

The logic circuit in Figure 3 has two inputs, A and B, and one input C. The output is Z. Looking at the circuit, we can see that the input C is connected directly to the output Z. This means that the value of C will always be present in the output Z, regardless of the values of A and B. The two inputs A and B are connected to an OR gate, and the output of the OR gate is connected to a NOT gate. The NOT gate inverts the output of the OR gate, which means that if the OR gate output is 0 (i.e., A and B are both 0), then the NOT gate output will be 1. Conversely, if the OR gate output is 1 (i.e., at least one of A or B is 1), then the NOT gate output will be 0. So, the overall logic equation for the circuit is: Z = \(\overline{A+B}\) \(\overline{C}\) In other words, the output Z is the logical NOT of the OR of A and B, ANDed with the logical NOT of C.
