Question:What are the address ranges for the following circuits? 

This image depicts a digital logic circuit often used in educational contexts to illustrate fundamental principles of logic gates and circuit design. The circuit includes AND and OR gates and represents the function of these gates to produce an output signal, typically used in selection or control mechanisms. ### Detailed Explanation: - **Inputs**: - \(A_{19}\): An input line to the AND gate. - \(A_{18}\): Another input line to the AND gate. - \(A_{16}\) and \(A_{14}\): Input lines to the OR gate. - **AND Gate**: - The two inputs, \(A_{19}\) and \(A_{18}\), are fed into an AND gate. An AND gate produces an output of logic high (1) only if both of its inputs are also logic high (1). - The output of the AND gate feeds into an OR gate. - **OR Gate**: - The OR gate takes three inputs: \(A_{16}\), \(A_{14}\), and the output from the AND gate connected to \(A_{19}\) and \(A_{18}\). - The OR gate outputs logic high (1) if at least one of its inputs is logic high (1). - **SEL Signal**: - The output of the OR gate is labeled as \( \overline{\text{SEL}} \). This indicates that the final result is a logically inverted signal (using a NOT operation) of the OR gate’s output. ### Operation Summary: - **Step 1**: The AND gate computes the logical AND of \(A_{19}\) and \(A_{18}\). - **Step 2**: The OR gate computes the logical OR of \(A_{16}\), \(A_{14}\), and the output from the AND gate. - **Step 3**: The output signal \( \overline{\text{SEL}} \) is derived by inverting the result of the OR gate’s output. This circuit could be used in situations where a specific selection (SEL) or control signal is needed based on multiple input conditions, useful in various digital electronics applications.
