Questions & Step-by-Step Solutions
In a multiplexer, what is the role of the select lines?
Step 1: Understand what a multiplexer is. A multiplexer is a device that can take multiple input signals and send one of them to the output.
Step 2: Know that a multiplexer has several input lines. Each input line can carry a different signal.
Step 3: Learn about select lines. Select lines are special control lines that help choose which input line to connect to the output.
Step 4: Realize that the number of select lines determines how many input lines can be controlled. For example, 2 select lines can control 4 input lines (2^2 = 4).
Step 5: When you set the select lines to a specific combination, it tells the multiplexer which input line to connect to the output.
