Course Learning Objectives
Students are expected to demonstrate the ability to:
• Learn the fundamental concepts of a digital telecommunication system.
• Characterize sampling and quantization of analog signals to generate
pulse modulation.
• Analyze baseband transmission of digital signals.
• Study the geometric representation of signals.
• Analyze and design passband digital communications techniques.
• Describe the architecture of common digital communication systems.
• Determine the bit error rate of basic modulation formats when operating
in white Gausian Noise environments.
• Determine the advantages of error correcting codes on the performance
of digital communication systems.
• Design digital communication systems to operate in noisy environments
and to achieve basic system specifications on bandwidth usage, data
rate, and error rate performance.
• Understand basic concepts of source coding.
