IMS method • Write down the minterms • These should be positive and ordered , ri>=N(1)/N(0) , this ratio in each column should be r 1>=r 2>=r 3>=r 4>=r 5>=1 • Write it down in the IMS chart • Select Nested F’s • Realize each zone by Dertouzo’s method • Connect with the help of OR gate(I/p +1, -1) IMS method 4
