Design a magnitude comparator that is able to detect whether ? > ?, ? = ?, ? < ?, where ? and ? are two 4-bit binary numbers. Use equations to design the circuit instead of truth table (truth table becomes length approach).
Hint: You may first design a 1-bit comparator, and extend it to design 2-bit comparator. Now use the same method of extension to design 4-bit comparator from 2-bit comparator.
Answer:-
we have three sections in the above figure which is seperated by black coloured line.
-> the first section represents the 1-bit comparator
-> the second section represents the 2-bit comparator
-> the third section represents the 4-bit comparator.
by combining all this section and by using 1-bit comparator and 2-bit comparators we had created 4-bit comparator.
please do thumb up
Thank you.

#5 Design a magnitude comparator that compares two 2-bit numbers, A and B. The system has three outputs that indicate whether A>B, A=B, or A <B. Draw your design with only XNOR, AND, and OR gates. 15
A magnitude Comparator is a combinational circuit that compares two binary numbers in order to find out whether one binary number is equal, less than or greater than the other binary number. Design a 2-bit binary magnitude comparator, using k-maps , simplify it and draw circuit.
A Y = A+ B 1 1 1 1 1 1 Apply the idea of the truth table above and design a 3-bit comparator using XOR or XNOR gates of your choice. The design should be able to determine the equality between two 3-bit words. An LED should be turned ON only when every bit in "Word A" matches every corresponding bit in "Word B". Otherwise, the LED has to be OFF Hint for I/O port Definitions: Port Name MSB...
Need help with this digital logic problem please show work for all parts thanks [2] [20 points] A 2-bit Binary Comparator logic circuit receives 2-bit numbers, P = P.P, and Q = Q.Qo, and has three outputs Y2, Y1, and Yo: Output Y2 is 1 if and only if P < Q, otherwise it is 0. Output Y1 is 1 if and only if P > Q, otherwise it is 0. Output Yo is 1 if and only if P...
3. Design a 4-bit combinational circuit that will detect if the input value is either a multiple of 3 (0,3,6,…) or a multiple of 4 (0,4,8,…). Draw the truth table, derive the simplified SOP Boolean expression and draw the simplified circuit.

Problem 4 Design the static complementary CMOS implementation of a 2-bit comparator circuit, where we have two inputs A and B (each is 2-bit wide) and the output 0 if A > B and output 1 if A B. Design the circuit for minimum delay (assuming a stage effort of 4) and driving a load of 10 fF. As part of the design you need to determine the width of all transistors You can use the following transistor parameters for...
