What does minimal SOP refer to in digital logic design?

• A. To combine the zeros and negate maxterms
• B. To combine the ones and maintain minterms
• C. To maximize the number of gate levels
• D. To initialize all terms with zeros

Answer: (B)

Minimal SOP, or Minimal Sum of Products, refers to the process in digital logic design where a Boolean function is expressed by combining the ones of the truth table to form the simplest possible expression. This means maintaining the minterms, which are the products (AND terms) that correspond to the binary value of 1 in the truth table. In digital design, achieving a minimal SOP expression is crucial because it directly impacts the efficiency of circuit implementation. A simplified SOP leads to reduced complexity in terms of the number of gates and connections required, ultimately resulting in a more cost-effective and reliable circuit design. This concept is foundational in minimizing logic functions, where the aim is not only to represent the function but also to do so in a way that uses the smallest number of logic gates. The distinction here embodies the essence of minimal SOP: focusing on the simplification of the logical expression while keeping a clear reference to the defined conditions (the ones) of the function's output.
