Questions & Step-by-Step Solutions
In modulation, what does the term 'carrier signal' refer to?
Step 1: Understand that modulation is a process used in communication systems.
Step 2: Know that in modulation, we need a way to send information over distances.
Step 3: The 'carrier signal' is a basic signal that can be changed to carry information.
Step 4: Think of the carrier signal as a vehicle that transports the information to its destination.
Step 5: The information is added to the carrier signal by changing its properties, like its amplitude or frequency.
Carrier Signal – A carrier signal is a waveform (usually a sine wave) that is modulated with an information signal to transmit data over a communication channel.
