In a magnitude comparator, what is the output when the two binary numbers being compared are equal?a.A < Bb.A = Bc.A > Bd.Undefined

To determine the output of a magnitude comparator when two binary numbers being compared are equal, we need to understand how a magnitude comparator functions.

A magnitude comparator compares two binary values, say $A$ and $B$. The outputs typically indicate whether $A$ is less than, equal to, or greater than $B$.

1. Understanding the Outputs:

   • If $A < B$, the output is true for that condition.
   • If $A = B$, the output will indicate this equality.
   • If $A > B$, the output is true for that condition.

2. Evaluating the Given Options:

   • a. $A < B$ — This is not true if $A$ and $B$ are equal.
   • b. $A = B$ — This is the correct output when both numbers are equal.
   • c. $A > B$ — This is not true if $A$ and $B$ are equal.
   • d. Undefined — This is incorrect in this context as the output is defined.

Final Answer

When the two binary numbers being compared are equal, the output of the magnitude comparator is $b. A = B$.
