What is the purpose of a demodulator in a communication system?
Steps
Concepts
Step 1: Understand that communication systems send information over distances.
Step 2: Know that information is often changed into a modulated signal to be sent.
Step 3: Realize that modulation is like putting the information into a special package for delivery.
Step 4: Learn that a demodulator is a device that takes the modulated signal out of its package.
Step 5: Understand that the demodulator converts the modulated signal back to its original form, which is called the baseband signal.
Step 6: Recognize that this original form can then be processed or understood by the receiving device.
