Expected Outcome(s):
  • Develop and employ circuit models for elementary electronic components, e.g., resistors, sources, inductors, capacitors, diodes and transistors.
  • Analyze TTL, ECL and CMOS logic inverters.
  • Understand the operation of latch circuit and flip-flop circuits, and of different types of semiconductor memories.
