Function R is given by the following equation: (,,,,)= (10,11,15,16,26,27,28,31)+ (0,3,12,19,20,30) Use Quine-McCluskey method to obtain all possible minimal SOP equation(s) for R. Make sure to do the following: a) Show all your work to obtain the resulting PIs (clearly, neatly and legibly write all the passes used in the first major step of the method) b) Clearly mark the EPIs on the PI chart (you can use an asterisk to denote EPIs) c) Clearly mark any PI chosen for your final answer (and enclose your final answer) d) Answer this question: Is the solution unique? If not, how many SOP solutions are there? e) If solution not unique, give another possible minimal SOP equation (besides the one given on part c)
