How can a multiplexer be used to implement an arbitrary Boolean function of its select lines?
Correct! Well done.
Incorrect.
The correct answer is A) By connecting the multiplexer's select lines to the function's input variables and wiring each data input to the constant (0 or 1) that the function should output for that corresponding input combination, as read directly from the truth table
Correct Answer
By connecting the multiplexer's select lines to the function's input variables and wiring each data input to the constant (0 or 1) that the function should output for that corresponding input combination, as read directly from the truth table
Since a multiplexer routes one of its data inputs to the output based on the select lines, setting each data input to the desired truth-table output value for that select combination directly realizes the function — a technique sometimes used for quick combinational logic implementation.
