Testbook Test Series Question
f(A,B,C,D)=∏M(0,1,3,4,5,7,9,11,12,13,14,15) is a max-term representation of a Boolean function f(A,B,C,D) where A is the MSB and D is the LSB. The equivalent minimized representation of this function is (A+C¯+D)(A¯+B+D)(A+C¯+D)(A¯+B+D) AC¯D+A¯BD+A¯BC A¯CD¯+AB¯CD¯+AB¯C¯D¯ (B+C¯+D)(A+B¯+C¯+D)(A¯+B+C+D)
