Hey everyone, I'm currently stuck on a lab that I have to complete for an online class I'm taking. I can't seem to wrap my head around it and my professor is incredibly hard to reach. I've attached a photo of my circuit on the breadboard, the procedure steps, and the incomplete schematic and truth table for the report.
My issue is that I don't understand how to determine the input of the multiplexer (D0-D7). I understand that my selector inputs will determine which input will pass through to the output, but how do I determine if my input should go to 0,1, B1, or B'1 as step 2 states. I'm also unsure of how to complete column X of the truth table. It seems like the output is determined by whether or not my jumper to the multiplexer inputs is going through the inverter or not.
I'm sure there's a simple explanation to this, but I need a little guidance in the right direction. Thanks.
