Task: Design a 2 bit comparator.
Input: 2x 2 bit (I take it as 2 2-bit values, let them be unsigned for simplicity) Output: 1 if result input1>input2 is true, 0 otherwise
Develop truth table and derive circuits.
The problem: I'm completely new to this so I have not even a idea where where to look for the lighthouse.
The question: I'M NOT LOOKING FOR COMPLETE SOLUTION, instead I'm looking for a guidance through topics/materials which I should check to be able to solve it myself.
Done so far: I started with understanding logical gates and those seem to be pretty straight forward.
P.S.: Purpose of posting this question is to boost the speed with which I will get to the actual solution.
SOLUTION: f(A,B,C,D) = !AB!C!D + A!C + ABC!D. (! - used for negation or NOR, ABC notations means A AND B AND C). I had three adjacent rectangles two of which were of unit cell size and one of 4 cells size (one cell was actually far away, but there's this toroidally connection property, not sure about terminology). A and B are MSD and LSD of the first number respectfully and B and C are same for second number. As for the circuit image: sorry folks my hand drawing requires strong mental stability.
