Course description
Digital circuits are widely applied to network communication devices and domestic appliances, etc. and support today's information society. A complex digital device is actually composed of simple elements. This course first introduces logical operation which is the basis of digital systems. It then deals with realization of Boolean expression using basic logic gates. Design and application of combinational logic (encoder, decoder, etc.) and sequential logic (flip-flop, register, counter, etc.) are also addressed.
Purpose of class
The purpose of this course is to help students understand the operation of building blocks of digital circuits. It also aims to improve student's ability to apply analysis methods to the circuits.
Goals and objectives
  1. To use the laws of Boolean algebra
  2. To explain the function of logic gates
  3. To explain the principle and operation of flip-flops
  4. To design combinational logic circuits
  5. To design sequential logic circuits
