    hi guys,
    I have a project due next week, and can't for the life of me understand how to use the 8-to-1 multiplexer.

    Can anyone give me a hint on how to get started on the project?

    I need to design a system, using 8-to-1 mulitplexers, that accepts 4 bit inputs and produces an output of 1 when the input is exactly divisible by 3 or 4. O is assumed to be divisible by 3 or 4.

    Thanks in advance for any help.

    Think about the way the multiplexer works. It takes a 3 bit code and uses that to select one of the 8 inputs, which will appear at the output. Think about arranging the inputs to give the correct output for the selection input.
