21. The objective of using Boolean algebra in digital-computer
a. (A+B+C) D
study is to determine the 'truth value' of a combination of two
b. (EF) +G
or more statements. For any Boolean function, there is a
c. (H+J) K(L+M)
corresponding truth table, which shows in tabulated form the
d. N+(OPQ)
true condition of the function for each occasion in which
conditions can be assigned to its variables. In binary
Boolean algebra, 0 and 1 are the symbols assigned to the
variables of any function.

22. In designing logic circuits for a computer, the first step is to
construct a truth table. The truth table not only provides a
ready reference for use in analyzing the operating theory of
the circuit, but also is useful in developing the overall signal-
flow diagram.
