How do you implement 8-bit comparator using two 4-bit comparators?

set the < , =, > as "010" and connect the lower bit that you want to compare to the first comparators and connects its output to the input of second comparator like this; connect the P<Q to < , and P=Q to = and P>Q = > (cascading input is checked for when P and Q are equal; the input from cascading input is set to the output "010"
