Produce the truth table of the combination of four NOR gates arranged as shown in Fig.
Text Solution
Verified by Experts
Output of gate I is `y^(')=bar(A+B)` Output of gate II is `y_(1)=bar(A+y^('))` Output of gate III is `y_(2)=bar(B+y^('))` Output of gate IV is `y=bar(y_(1)+y_(2))` The truth table of the combination is given below: `:|{:(A,B,y'=bar(A+B),y_(1)=bar(A+y'),y_(2)=bar(B+y'),y=bar(y_(1)+y_(2))),(0,0,1,0,0,1),(1,0,0,0,1,0),(0,1,0,1,0,0),(1,1,0,0,0,1):}:|`
