Study Notes
Key Concepts in Frequency Modulation
- In frequency modulation (FM), the frequency of the carrier wave is altered to encode information.
- The amplitude of the carrier wave remains constant during frequency modulation.
- Frequency modulation aims to provide a robust communication signal that is less susceptible to interference and noise.
- The process of altering the carrier frequency based on the modulating signal is referred to as frequency deviation.
- Frequency modulation is particularly known for its noise-suppression effects, making it ideal for broadcasting and communication systems.
