Design 1 Bit Comparator Circuit

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.
Design 1 bit comparator circuit. A b a b a b figure 2 1 1 bit comparator. A comparator is shown as figure 2 1. The truth table for a 4 bit comparator would have 4 4 256 rows. The output of comparator is usually 3 binary variables indicating.
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. 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. So we will do things a bit differently here. I ii iii 1 bit comparator implementation using logic gate.
2 logic design for 4 bit comparator 2 1 logic design procedure magnitude comparator is a combinational circuit that compares to numbers and determines their relative magnitude. In general a comparator is a device which compares two currents or voltages and produces the digital output based on the comparison. Consider one bit number a and b trust table is shown below. The logic circuit of a 2 bit comparator how to design a 4 bit comparator.
