Introduction
The term digital is derived from the way operations
are performed, by counting digits. For many years,
applications of digital electronics were confined
to computer systems. Today, digital technology is
applied in a wide range of areas in addition to com-
puters. Such applications as television, communi-
cations systems, radar, navigation and guidance
systems, military systems, medical instrumentation,
industrial process control, and consumer electron-
ics use digital techniques. Over the years digital
technology has progressed from vacuum-tube circuits
to discrete transistors to complex integrated circuits,
many of which contain millions of transistors, and
many of which are programmable.
