You do not need to understand anything about circuits
or electricity to be able to answer these questions.
These problems ask about the basic notation the symbols
used when drawing circuits. You should be able to work
all of these problems even if they are not assigned.
You do not need to understand anything about circuits
or electricity to be able to answer these questions.
These problems ask about basic circuit diagrams.
If you do not recognize the circuit, then begin with
a truth table, and then compare with Table 3.5 or Table
3.9.
These problems ask about basic gate diagrams.
See Example 2.
See Example 2; notice that these all involve implication,
so you may need to review Table 3.6.
See Examples 2 and 3.
The difference
between these problems and Example 2, is there are
three propositions, so the truth tables will have
eight entries.
However, as you go through the book be sure you
look at all the examples in the text. If you need hints
for the Level 3 problems, check some sources for help
on the internet (see the LINKS for that particular section.

On the other hand, the problems designated "Problem
Solving" generally require techniques that do not have
textbook examples.
