单词 Boolean function
释义
Boolean function

Computer
  • A function in Boolean algebra. The function is written as an expression formed with binary variables (taking the value 0 or 1) combined by the dyadic and monadic operations of Boolean algebra, e.g.

    f=(xy)(xz)
    For any particular values of its constituent variables, the value of the function is either 0 or 1, depending on the combinations of values assigned to the variables. A Boolean function can be represented in a truth table. It can also be transformed into a logic diagram of logic gates. See also product of sums expression, sum of products expression.


Electronics and Electrical Engineering
  • A function whose inputs and output are Boolean values. The AND, OR, and NOT operators of Boolean algebra are such functions, taking either two Boolean inputs (AND, OR) or one (NOT), and all producing a single Boolean output. Both NAND and NOR circuits can also be considered as implementing Boolean functions.
