Now, using the 1-bit magnitude comparator and other gates (if necessary) as building blocks, model the 2-bit magnitude comparator in VHDL through component This basic circuit for a So I got this We can then combine two 4-bit Results of 2-bit comparator operation obtained through BPM, when magnitude of B is (a) 0 (b) 1 (c) 2 (d) 3 and magnitude of A changes from 0 to 3. One -bit Magnitude Comparator: A comparator used to compare two 1-bit binary numbers. Posted 2 months ago. [15] Design a 2-bit magnitude comparator as depicted below. A comparator is a combinational logic circuit that compares two inputs and gives an output that indicates the relationship between them. Specifically, create a truth table and then obtain minimal Boolean equations in SOP form for each output of the comparator. Click to share on Twitter (Opens in new window) Click to share on Facebook (Opens in new window) The truth table for a 4-bit comparator would have 4^4 = 256 rows. So we will do things a bit differently here. 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. 2 bit comparator. View Answer . 1-Bit Magnitude Comparator - The Digital Comparator is another very usefulcombinational logic circuit used to compare the value of two binary digits. The logic circuit of a 2-bit comparator How to design a 4bit comparator? 2-bit comparator. The output of comparator is usually 3 binary variables indicating: A>B A=B AB A=B AB and gate 3 gives AB, A
