| Sep 16, 2021 at 15:35 | comment | added | Solomon Slow | Re, "why exactly do we need four?" You need four bits because your professor said so. That's an external requirement -- a design choice that is forced on you by somebody else. In the real world, the output of your circuit would be an input to some other circuit. If you wanted to know "why 4 bits?" you'd ask the designer of that other circuit. If you wanted to negotiate a different number of bits, that's who you'd talk to. Maybe their design still would be open to change, maybe not. | |
