Q
Q: What is the primary purpose of a demodulator in a communication system?
Solution:
A demodulator converts the modulated signal back to its original form.
Steps: 5
Show Steps
Step 1: Understand that in communication systems, information (like voice or data) is sent over a medium (like air or cables).
Step 2: Know that this information is often changed into a different form called a 'modulated signal' to make it easier to send.
Step 3: Realize that a demodulator is a device that takes this modulated signal.
Step 4: Learn that the demodulator's job is to change the modulated signal back into the original information form.
Step 5: Conclude that the primary purpose of a demodulator is to recover the original information from the modulated signal.
