Final answer:
The XNOR gate acts as a logical either/or operator followed by a NOT gate.
Step-by-step explanation:
The logic gate that acts as an logical either/or operator followed by a NOT gate is the XNOR gate. The XNOR gate is a type of gate that outputs true only when the number of true inputs is even. In other words, it acts as an equality comparator. It can be represented by the logical expression (A XOR B) or (A XNOR B), where A and B are the inputs.
For example, if A is true and B is false, the XNOR gate will output false. If both A and B are true or if both A and B are false, the XNOR gate will output true.
The XNOR gate can be implemented using other logic gates, such as the XOR gate followed by a NOT gate. This combination acts as an either/or operator followed by a NOT gate and produces the same output as the XNOR gate.
