Q.1

The observation that a bubbled input OR gate is interchangeable with a bubbled output AND gate is referred to as:

  • a Karnaugh map
  • DeMorgan's second theorem
  • the commutative law of addition
  • the associative law of multiplication

Q.3

The systematic reduction of logic circuits is accomplished by:

  • symbolic reduction
  • TTL logic
  • using Boolean algebra
  • using a truth table
Q.4

The commutative law of addition and multiplication indicates that:

  • the way we OR or AND two variables is unimportant because the result is the same
  • we can group variables in an AND or in an OR any way we want
  • an expression can be expanded by multiplying term by term just the same as in ordinary algebra
  • the factoring of Boolean expressions requires the multiplication of product terms that contain like variables
