Can we design 2 bit comparator using logic gates?
Comparator – Designing 1-bit, 2-bit and 4-bit comparators using logic gates. A Comparator is a combinational circuit that gives output in terms of A>B, A
What is magnitude comparator in digital logic design?
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.
What are the applications of 1 bit and 2 bit comparator?
These are used in control applications in which the binary numbers representing physical variables such as temperature, position, etc. are compared with a reference value. Comparators are also used as process controllers and for Servo motor control. Used in password verification and biometric applications.
What is the function of comparator and how it compares the two binary numbers?
A magnitude digital comparator is a combinational circuit that compares two digital or binary numbers (consider A and B) and determines their relative magnitudes in order to find out whether one number is equal, less than or greater than the other digital number.
How is a 1 bit magnitude comparator used?
1-Bit Magnitude Comparator – A comparator used to compare two bits is called a single bit comparator. It consists of two inputs each for two single bit numbers and three outputs to generate less than, equal to and greater than between two binary numbers. The truth table for a 1-bit comparator is given below:
How is a comparator used in a logic circuit?
A comparator is a combinational logic circuit that compares input bits and gives an output that indicates the equality/inequality.
Which is the 4 bit comparator in CMOS logic?
These are available in TTL as well as CMOS logic family ICs and some of these ICs include IC 7485 (4-bit comparator), IC 4585 (4-bit comparator in CMOS family) and IC 74AS885 (8-bit comparator). A comparator used to compare two bits, i.e., two numbers each of single bit is called a single bit comparator.
How many output terminals does a magnitude comparator need?
Comparators with three output terminals and checks for three conditions i.e greater than or less than or equal to is magnitude comparator.
