Course Outcome

After learning the course the students should be able to:

  • Understand about various types of signals, classify them, analyze them, and perform various operations on them.
  • Understand about various types of systems, classify them, analyze them and understand their response behavior.
  • Appreciate use of transforms in analysis of signals and system.
  • Carry simulation on signals and systems for observing effects of applying various properties and operations.
  • Create strong foundation of communication and signal processing to be studied in the subsequent semester
