True or False. Frequency Modulation (FM) involves encoding information into a carrier wave by varying the amplitude of the wave.

True or False. Frequency Modulation (FM) involves encoding information into a carrier wave by varying the amplitude of the wave.

• A. True
• B. False
• C. Partially True
• D. Depends on the modulation type

Answer: (B)

Frequency Modulation (FM) is a technique used to encode information in a carrier wave by varying the frequency of that wave, not the amplitude. In FM, the amplitude of the carrier wave remains constant while the frequency changes in accordance with the information being transmitted. This method is known for its resilience to noise and inference compared to amplitude modulation (AM), where the information is encoded in variations of amplitude. Therefore, the statement is false because it inaccurately describes FM as encoding information through amplitude variation, which is a characteristic of amplitude modulation rather than frequency modulation. Understanding these distinctions is crucial for working with communication systems that utilize various modulation techniques.
