Chapter 4 - Combining Logic Gates
Chapter Overview
In Chapter 3 you memorized
the symbol, truth table, and Boolean expression for each
of the binary logic gates. These gates are the basic building
blocks for all digital systems.
In this chapter you will see how your
knowledge of gate symbols, truth tables, and Boolean expressions
can be used to solve real world problems in electronics.
You will be connecting gates to form what engineers refer
to as combinational logic circuits, and you will be combining
gates (ANDs, ORs) and inverters and so on to solve logic
problems.
There are three 'tools of the trade'
in solving logic problems: gate symbols, truth tables, and
Boolean expressions. Do you have these tools of the trade?
Do you know your gate symbols, truth tables, and Boolean
expressions?
If you need review on logic gates, please
refer to the summary of Chapter 3; Figure 3-56 (p. 71) especially
will be helpful. Your understanding of using logic gates
is important because to be successful as a technician, troubleshooter,
engineer, or hobbyist in digital electronics you must master
combining gates.
It is strongly suggested that you
try out your combinational logic circuits in the shop or
laboratory. Logic gates are packaged in inexpensive, easy-to-use
ICs. Combinational logic circuits can be implemented using
either TTL or CMOS ICs. Combinational logic circuits can
also be implemented using circuit simulation software on
your computer.
