Use K mapping to design a circuit to meet the requirements of Example 4-17. Compare this circuit with the solution in Figure 4-23. This points out that the K-map method cannot take advantage of the XOR and XNOR gate logic. The designer must be able to determine when these gates are applicable.

Data from Example 4-17

The notation x₁x₀ represents a two-bit binary number that can have any value (00, 01, 10, or 11); for example, when x₁ = 1 and x₀ = 0, the binary number is 10, and so on. Similarly, y₁y₀ represents another two-bit binary number. Design a logic circuit, using x₁, x₀, y₁, and y₀ inputs, whose output will be HIGH only when the two binary numbers x₁x₀ and y₁y₀ are equal.
