## circuit diagram of 4 bit comparator

The circuir diagram of a single stage camparator for 8 bits would be extremely complicated, instead u can use two four-bit-comparators in vascade. These comparators are really easy to design drawing upon Karnough Maps. PM me if u dont know how to design these.

## ppt 5 bit comparator

There is 7485 - 4-bit comparator, but they can be cascaded for more bits (there is internal schematic) :
