Obtaining HIGHER COMPARATOR using LOWER COMPARATORS
Q-Can we implement higher comparator 4-bit comparator using 2-bit comparators. Ans: Yeswe can implement the above required as follow: Firstly lower two bits of A & B are compared and then next bits and then next. We feed the result of first 2 bits to lower bit of next comparator. Then we feed the result […]
2-bit COMPARATOR
Similarly we can have 2 bit comparator and the table to list all the combinations at input and their corresponding outputs is as: A B f (A>B) f (A=B) f (A<B) 00 00 0 1 0 01 00 1 0 0 10 00 1 0 0 11 00 1 0 0 00 01 0 0 […]
1 bit COMPARATORS
Here we’ll be designing circuits to compare different binary numbers. Suppose we have two numbers A & B at the input and 3 output as A>B, A=B, A<B and only one of the three outputs would be high accordingly if A is greater than or equal to or less than B. 1-bit comparator: Let’s begin with […]
