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 […]
