A comparator with two inputs A and B subtracts A from B and inspects the sign of the result: Y(A, B) := sign(A-B)

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"


What do comparators do?

Why the internal resistance should be high in operational amplifiers?

High input impedance implements the operation of the external feedback circuitry (e.g. diff. amplifiers vs. comparators).


What if same inputs are given to the comparator?

If the same inputs are given to a comparator, the output will typically indicate that the inputs are equal. For digital comparators, this means the output signal will reflect a logical state that signifies equality, while for analog comparators, the output will show no difference between the input values. This behavior is essential for applications requiring precise comparisons, such as sorting or decision-making processes.

How do you divide a bigger number into a a smaller number to find the percentage?

Not necessarily, you need to look at the context of the percentage you are finding. For example, in machines, when finding percent efficiency, the output can be greater or less than the input, the output is divided by the input so sometimes the number may be greater or smaller. However, in the case of merchandise sales, you do not find sales that are greater than 100% off so it would actually be the smaller number divided by the bigger number.

How do you realize a higher magnitude comparator using lower bit comparators?

Well, honey, to realize a higher magnitude comparator using lower bit comparators, you simply cascade multiple stages of comparators together. Each stage compares a subset of bits, and the outputs are then fed into the next stage until you cover all the bits you need. It's like building a ladder one step at a time to reach the top - ain't rocket science, just good ol' fashioned engineering.
