2 Bit Comparator Circuit Diagram. Block diagram of n bit magnitude comparator the circuit for comparing two n bit numbers has 2n inputs 2 2n entries in the truth table for 2 bit numbers 4 inputs 16 rows in the truth table similarly for 3 bit numbers 6 inputs 64 rows in the truth. Introduction in this report it is clearly illustrated how to design a 2 bit comparator circuit.
Design had been successfully tested by proteus simulation software. A magnitude digital comparator is a combinational circuit that compares two digital or binary numbers in order to find out whether one binary number is equal less than or greater than the other binary number. Ni multisim live lets you create share collaborate and discover circuits and electronics online with spice simulation included this site uses cookies to offer you a better browsing experience.
The truth table for a 4 bit comparator would have 4 4 256 rows.
We logically design a circuit for which we will have two inputs one for a and other for b and have three output terminals one for a b condition one for a b condition and one for a. The result is displayed on a 7 segment. Introduction in this report it is clearly illustrated how to design a 2 bit comparator circuit. 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.
