7. a. W
A switching network which contains four switches represented
by variable C will have __________________ switches closed
when function C is present.
10. The figure below represents a switching network which
contains four individual switches. Notice that two of the
switches are represented by the same variable, X.
When the function of variable X is present for this network,
__________________________ represented by variable X will
(both switches/only one switch)
11. A Boolean expression can be written for switching circuits after
first determining which combination of switches must be caused
to obtain an output. For example, the AND circuit of two
switches (variables) is shown below.
