Digital Logic Design

Course Synopsis

Digital Logic Design is a technological subject which is intended to make students familiar with different types of designs as sequential logic circuits, combinational logic circuits, trouble shooting of various digital systems, study of various digital systems. It is an introductory electronics course covering Basic Electron Theory, Resistors, Analog and Digital Waveforms, Number systems, Conversions, Logic Gates, Boolean Algebra, Combination Circuit Design, Flip-Flops, Shift Registers and Counters. After reading this course students would have complete understanding about the low level architecture of any digital system of diverse areas like computer systems, telephony, data processing system, radar, navigation, military systems, medical instruments, process controls etc.

Course Learning Outcomes

At the end of the course, you should be able to:

  • Identify and work with different number systems and codes.
  • Discuss logic gates, combinational circuits, Boolean Algebra.
  • Know how Boolean expressions are simplified using Karnaugh maps.
  • Design different combinational circuits like comparator, adders and detectors etc using different simplification methods.
  • Understand encoder, decoders, multiplexers and demultiplexers.
  • Understand the working of latches, flip flops, synchronous and asynchronous counters, clocks, shift registers.
  • Understand memory architecture and basic operations.
  • Understand the working of flash memory.
  • Describe the working of analogue to digital and digital to analogue converters.
