Digital Communications (2020)
The intent of the Digital Communications Knowledge Unit is to provide students with knowledge of the protocols and methodologies used in modern digital communications systems.
To complete this KU, students should be able to:
- Describe digital communications systems in terms of subsystems and modulation techniques.
- Describe the current state of the art in digital communications.
- Compare and contrast different approaches to digital communications and describe the advantages and disadvantages of each.
Cohesive combination of select topics from the following:
- Components of a digital communications system
- Coding schemes
- Pulse Amplitude Modulation
- Return to zero
- Non-return to Zero
- Bipolar Return to Zero
- Digital Signaling
