Frequency Modulation

Real World Example

Imagine trying to communicate with a friend across a crowded, noisy room by waving your arms in different patterns. This is similar to frequency modulation, where information is transmitted by altering the frequency of a wave, much like you change your arm movements to convey different messages. Just as you might wave quickly to signal urgency or slowly to indicate calmness, frequency modulation involves varying the frequency of a carrier wave to represent different pieces of information, allowing your message to stand out amidst the background noise.
