B b3b2b1b0 three outputs reporting greater than less than and equal respectively a3 b3 a2 b2 a1 b1 a0 b0 0 0 1 a3 b3 a2 b2 a1 b1 a0 b0 0 1 0 a3 b3 a2 b2 a1 b1 a0 b0 1 0 0. We will compare each bit of the two 4 bit numbers and based on that comparison and the weight of their positions we will draft a truth table.
It consists of four inputs and three outputs to generate less than equal to and greater than between two. 3 bit logic diagram 4 bit magnitude comparator. The output is a b in the cases of.
The figure below shows the block diagram of a single bit magnitude comparator.
Magnitude comparator for 1 bit 2 bit 3 bit 4 bit are discussed in this lecture the expressions for outputs of 1 bit 2 bit 3 bit and 4 bit magnitude comp. With an epicenter 0 7 miles from concord 2 4. The truth table for a 4 bit comparator would have 4 4 256 rows. 3 bit logic diagram 4 bit magnitude comparator.
