What is modulation?
Show hintHide hint
Think about how we send information over communication channels.
Question 2.
Name one type of modulation.
Show hintHide hint
There are common types used in radio broadcasting.
3Question 3.
What is the purpose of modulation?
- To protect data from noise
- To encode digital data onto an analog signal

Remember what happens after modulation.
Question 5.
Design a scenario where modulation is essential in communication. Describe the modulation technique and why it's chosen.
Show hintHide hint
Consider communications where distance and interference are factors.
Question 6.
Evaluate the impact of noise on a demodulated signal in a communication system.
Show hintHide hint
Think about how noise can change the original content of a signal.
