If A, B, and C_in are all select inputs, then why is C_in labeled differently? What is the distinction? See pic at very top
Later, in a separate problem, I get confused by this notation in another example http://i.imgur.com/CtlWbTI.png
Is S or Cout the "top decoder"? What "top decoder mean" ? Why do we still have this C notation and is Cout somehow related to Cin? Why distinguish S and Cout with different letters? Shouldn't I just have 2^n Cout outputs?
- There's mention of "other outputs" in this pic http://i.imgur.com/CtlWbTI.png
I only see two total outputs- S and Cout. But there should be 2^n outputs I thought
- Later in a totally different example problem in the link below that has answers but no solutions, I get more confused by the C and C bar as two inputs instead of a C_i and it looks we input S1, S0 twice in a row except the bottom time there is an A and a B associated with it. What does this notation mean? See below
