1. The problem statement, all variables and given/known data On the data sheet, name the device in Figure 9, and appropriately name the four pins A, B, C, and D according to what the device is. Check your Digital Logic book for some guidance. https://mail.google.com/mail/u/1/?ui=2&ik=ca64811c74&view=att&th=139f410abe33126b&attid=0.1&disp=inline&safe=1&zw 2. Relevant equations None 3. The attempt at a solution So I've set up a truth table for this equation and got A B C D 0 0 1 1 0 1 1 0 1 0 0 1 1 1 0 0 So having looked at this, it appears as if the two inputs are reversed. However, I'm not sure if there is an actual device out there that this represents, or just a configuration of gates. I've checked my books and nothing sticks out. Any ideas?
