•  Advantages of Digital Electronics 
 + Digital systems are generally easier to design 
 + Information storage is easy 
 + Precision is greater 
 + Operation can be programmed 
 + Digital circuits are less affected by noise 
 + More digital circuitry can be fabricated on IC chips 
•  Limitations 
 - Real world is mainly analog, so ADC and DAC 
 are required.

 Give insight in the design of digital electronic systems 
at the gate level and register-transfer level (RTL). 
 After this course, the students can design and analysis 
two kinds of digital logic circuits : Combinational Logic 
Circuits and Sequential Logic Circuits. They also 
understand and apply all basic modular logic circuits (in 
IC) to a digital system. 
  Introduction some modern design tools
