Q. Two 4-bit comparators are cascaded to form an 8-bit comparator. The cascading inputs of the most significant 4 bits should be connected. (Solved)
1. to the outputs from the least significant 4- bit comparator
2. to the cascading inputs of the least significant 4- bit comparator
3. a = b to a logic high, a< b and a > b to a logic low
4. ground
- a. to the outputs from the least significant 4- bit comparator
