3 Bit Magnitude Comparator Truth Table And Logic Diagram. 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. The logic circuit of a 2 bit comparator how to design a 4 bit comparator.
A comparator that compares two binary numbers each number having 4 bits and produces three outputs based on the relative magnitudes of given binary bits is called a 4 bit magnitude comparator. 3 bit logic diagram 4 bit magnitude comparator. 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.
The truth table for the single bit comparator is given below.
The output is a b in the cases of. 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. When a0 b0 00 11 both inputs are equal therefore a b output will be high. The logic circuit of a 2 bit comparator how to design a 4 bit comparator.
