OBJECTIVE OF THIS COURS
Digital design is concerned with the design of
digital electronic circuits. Digital circuits are
employed in the design and construction of
systems such as digital computers, data
communications, digital recording, and many other
applications that require digital hardware. This
course presents the basic tools for the design of
digital circuits and provides the fundamental
concepts used in the design of digital systems
3
The first step towards the intriguing digital
world!
Objective To introduce the fundamental concepts
of digital systems. To introduce the basic
techniques to analyze and design digital logic
circuits. To provide experience designing and
building digital logic circuits and programming
8-bit microcontroller.

• Outcome
• Able to design, analyze and debug basic digital
  systems
• Able to program simple microcontroller
• Ready to build a simple but real computer

Policies
Scheduling Conflicts If you have a conflict for a
scheduled Mid term exam with a lower number
course, see your instructor within the first
three days of class. Class attendance and class
participation are graded. So, at the end of the
semester, if a student is on a borderline between
grades, these factors will be considered when
deciding the final grade.

Analog values vary over a broad range
continuously
Digital only discrete values
13
Analog vs. Digital

• Analog devices process signal that can assume any
  value across a continuous range and produce
  results that are also in continuous form.
• Digital devices process signals that take on only
  two discrete values such as 0 and 1 and produces
  output that can be represented by 0 and 1.
• Examples
• Analog Devices solid-state devices TV (except
  for digital TV), Audio amplifier etc.
• Digital Devices Computer, CD player, digital TV,
  digital cellular phone, electronic calculator,
  and digital camera.

14
Analog vs. Digital Systems

• Analog systems
• Limited precision, errors accumulate, drift
• Interface circuits (i.e., sensors actuators)
  often analog

• Digital systems
• More accurate and reliable
• Readily available as self-contained, easy to
  cascade building blocks
• Computers use digital circuits internally

Research and Publication I am always being trying
to involved my self for published my thought as I
already published 12 (Twelve ) topics of
publication in world wide different IT Journal.
Also developing the characteristic of visual
signal and system analysis and design.
