1. Lecture on Digital Logic Design

2. 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

7. 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 day’s 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.

12. Analog vs. Digital Analog: values vary over a broad range continuously+5 +5 1 1
Time
Time –5 –5
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
