Question No: 1

Given below is the block diagram of a comparator circuit which compares two numbers (1^st no is A1Ao and 2^nd no is B1Bo) in such a way that Out put A>B will be 1 when 1^st no is greater than 2^nd no, output A=B will be 1 when 1^st no is equ

al to 2^nd number and output A^st no is less than 2^nd no. You have to give the truth table of this comparator system, simplified Boolean expressions using K-map for three outputs and the circuit

diagram for the whole syst
