Question #1838

Assume that a number comparator compares two numbers A and B of two bits each. The comparator output two bits – the first one output the result of comparison (1 if same 0 otherwise) and second one output 1 if both A and B are zero, otherwise 1. The partial truth table for the comparator is given below:<br><br>Number A& & & & & & & & & & & & & & & & & & Number B& & & & & & & & & & & & & & & & Output<br>Bit 1& & & & & Bit 0& & & & & & & & & & & Bit 1& & & Bit 0& & & & & & & & & Same& & & & Zero<br>0& & & & & & & & & & & 0& & & & & & & & & & & & & & & & & & & 0& & & & & & & 0& & & & & & & & & & & & & & & & & 1& & & & & & 1<br>0& & & & & & & & & & & 0& & & & & & & & & & & & & & & & & & & 0& & & & & & & 1& & & & & & & & & & & & & & & & & 0& & & & & & 0<br>0& & & & & & & & & & & 0& & & & & & & & & & & & & & & & & & & 1& & & & & & & 0& & & & & & & & & & & & & & & & & 0& & & & & & 0<br>0& & & & & & & & & & & 0& & & & & & & & & & & & & & & & & & & 1& & & & & & & 1& & & & & & & & & & & & & & & 0& & & & & & 0<br>0& & & & & & & & & & & 1& & & & & & & & & & & & & & & & & & & 0& & & & & & & 0& & & & & & & & & & & & & & & & & 0& & & & & & 0<br>0& & & & & & & & & & & 1& & & & & & & & & & & & & & & & & & & 0& & & & & & & 1& & & & & & & & & & & & & & & & & 1& & & & & & 0<br>…& & & & & & & & & & & & & & & <br><br>Complete the truth table and design and draw the combinational circuit using AND-OR-NOT gates for the description given above.&
