Consider an AM broadcast band that consists of 107 channels for stations 10kHz wide. The maximum permitted modulating frequency is 5kHz. Discuss whether FM could be used on this band. If so, explain what would be necessary to make it happen.

FM & Phase-Locked Loop

• Consider an AM broadcast band that consists of 107 channels for stations 10kHz wide. The maximum permitted modulating frequency is 5kHz. Discuss whether FM could be used on this band. If so, explain what would be necessary to make it happen.
• Discuss the three key components of a phase-locked loop and write a brief explanation of how each component works.

Nondigital Communications and Data Transfers

• Discuss the three major types of communication services that are not yet digital but could eventually be, and explain how digital techniques could be applied to those applications.
• Discuss the conditions under which serial data transfers are faster than parallel data transfers
