I don't even understand what they're asking me to do for these 2 problems, can someone please help me start on them?
1 - Find the simplest sum-of-products form for the function f using the don't care condition d where:
f= x_{1}(x_{2}(-x_{3})+-x_{2}(-x_{3})(-x_{4}))+(x_{2})(-x_{4})(-x_{3}+x_{1})
d= x_{1}(-x_{2})(x_{3}x_{4}+(-x_{3})(-x_{4}))+(-x_{1})(-x_{3})x_{4}
2 - Find a minimum cost implementation of the function f(x_{1},x_{2},x_{3},x_{4}) where f=1 if either 1 or two of input variables have the logic value 1. Otherwise f=0.
