Single-Course Danish 5 ECTS

Digital Electronics 1

Overall Course Objectives

To introduce the basics of digital electronics and to enable participants to specify, analyze, synthesize and implement simple digital circuits (combinatorial logic and finite state machines).

Learning Objectives

  • Explain the basic principles and underlying assumptions for synchronous digital circuits – the ‘discrete abstraction’ and the fundamental implementation using logic functions (combinatorial circuits) and memory elements (flip-flops etc.).
  • Explain the operation of the MOS-transistor as an ideal logic switch, and describe how transistors are used to implement CMOS logic (logic gates and memory elements).
  • Explain the basics of Boolean algebra and use it for describing, developing and reducing logic expressions – including the canonical forms: sum-of-products and products-of sums.
  • Transform between a logic expression and a digital circuit implemented using logic gates such as AND, OR, NOT, NAND and NOR.
  • Describe commonly used number and data representation formats and convert between different number representations.
  • Implement and operate small combinatorial circuits in the lab using discrete logic gates (simple 4000 components).
  • Explain the operation and implementation of fundamental arithmetic circuits and other typical combinatorial circuit building blocks (multiplexor, decoder, etc.).
  • Explain the operation and implementation of fundamental memory elements (D flip-flop’s and D-latches).
  • Calculate propagation delay (critical path) of a combinatorial circuit.
  • Explain the structure and operation of a finite state machine (Moore type), and explain step-by-step how such a finite state machine is designed (state graph, state table, state minimization, state encoding, etc.).
  • Transform a verbal description of an intended circuit into a specification using Boolean algebra, truth tables, state-graphs, etc., and subsequently to synthesize and implement the circuit.
  • Demonstrate basic knowledge about simulation and synthesis tools for digital circuits, including the ability to describe small combinatorial circuits using a hardware description language (such as VHDL).
