Communication and Controls


The first part of this course deals with Communication Systems. Basics of wireless communication technology such as frequencies used for communication, signal characteristics, antennas and different multiplexing and modulation schemes are introduced to help understand many design decisions in higher layers of mobile communication systems. Different wireless communication systems such as GSM, satellite communications, digital broadcast systems and wireless LAN is introduced. The second part of the course deals with the fundamentals of Control Systems. Different components of a control system, classifications including open loop and closed loop systems and mathematical representation of a physical system are covered. Time response of a system to an input signal, stability and frequency responses are then explained along with the basics of PID controllers. At the end, an introduction to digital control systems is given.

Student Learning Outcomes

On successful completion of this course, students will be able to:

  • Explain how cellular devices work and understand different technologies used in cellular communications such as GSM, CDMA, TDMA etc. and their pros and cons
  • Understand what a computer network is and explain various protocols such as TCP/IP, HTTP, FTP
  • Explain how local area networks (LAN), wide area networks (WAN) and wireless networks function
  • Understand how the controls function in systems such as refrigerators, furnaces, variable speed drives, heat exchangers, robots etc.
  • Describe the principles and characteristics of controllers used in motion and process control systems
  • Understand terms such as stability, bandwidth and time response in a control system used in common applications
