Suppose that, in the circuit for a 2-bit comparator, we wanted to allow for inputs from the higher byte comparisons, xHyH, so that we could now use a 2-bit comparator in cascades for building comparators for numbers with more than 2 bits. See the following diagram: a) Re-write the equations for a 2-bit comparator that would allow for the inputs: xHyH. b) Re-draw the corresponding circuit diagram. 141 Suppose that, in the circuit for a 2-bit comparator, we wanted to allow for inputs from the higher byte comparisons, xHyH, so that we could now use a 2-bit comparator in cascades for building comparators for numbers with more than 2 bits.
