Overview. This is usually achieved by converting the input symbols to Gray coded symbols and then mapping it to the desired QAM constellation. Derive the canonical sum-of products (sOP) . Karnaugh maps make use of the human brain's … By minimization we imply a function with minimum number of terms and each term with lowest number of literals. For the case when the Boolean function is specified by a circuit (that is, we want to find an equivalent circuit of minimum size possible), the unbounded circuit minimization problem was long-conjectured to be -complete, a result finally proved in 2008, but there are effective heuristics such as Karnaugh maps and the Quine–McCluskey algorithm that facilitate the process. This means that b is redundant and can be discarded this group. Minimization with Karnaugh Maps and advantages of K-map.
