Design 1 Bit Comparator Circuit

I ii iii 1 bit comparator implementation using logic gate. 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 output of comparator is usually 3 binary variables indicating.

So we will do things a bit differently here.

Design 1 bit comparator circuit.

The truth table for a 4 bit comparator would have 4 4 256 rows. 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. 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. Circuits that compare two voltages and give a digital output dependent upon the comparison of the two voltages are often used within electronic circuit design.

In general a comparator is a device which compares two currents or voltages and produces the digital output based on the comparison. For a comparator circuit a high gain amplifier is needed so that even small changes on the input result in the output level firmly switching. A comparator is shown as figure 2 1. The comparator is basically a 1 bit analog to digital converter.

The logic circuit of a 2 bit comparator how to design a 4 bit comparator. Consider one bit number a and b trust table is shown below. A b a b a b figure 2 1 1 bit comparator. 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.
