I'm trying to understand multiplexers (MUX) and I have a few questions that I hope someone can help me with.
I'm not sure what determines if the inputs to the MUX are multiplications (AND) or additions (OR). Can someone explain this to me?
I was wondering what difference it would make if I had CD as selector signals instead of the usual AB? I'm also having trouble understanding how to determine which of the combinations are horizontal or vertical on the K-map. Can someone explain this to me or point me in the right direction for more information? Any help would be greatly appreciated.
